Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A box-type solar cooker requires a material with good thermal conductivity (like copper) and an inner surface painted black to maximize the absorption of solar radiation.

Food gets cooked faster in a pressure cooker because ___________________.

  1. Water starts boiling at a higher temperature due to high pressure

  2. Water boils only at 100 °C but the heat content is higher at high pressure

  3. Water boils only at 100 °C but the heat content is higher at low pressure

  4. Convection currents are set inside the cooker
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A pressure cooker increases the pressure inside the vessel, which raises the boiling point of water. This allows the food to cook at a higher temperature, significantly reducing cooking time.

Multiple choice chemistry man made materials environmental impact: plastics plastic plastic plastic waste garbage in, garbage out

Cooking pans have plastic handles.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Plastics are categorized into thermosoftening/thermoplastic and thermosetting/thermoset plastics.
In thermosoftening plastics, the forces between the polymer chains are weak, so they can easily be remoulded into new shapes. This makes it possible to recycle this type of plastic. whereas in thermosetting plastics there are strong covalent bonds forming cross-links between the polymer chains, making these plastics hard and rigid. Once set into its original shape, a thermosetting plastic can't be softened and remoulded. The strong bonds between polymers also mean that thermosetting plastics are much more heat resistant than thermosoftening ones.
Cooking pans' handle are made from thermosetting plastic like bakelite as this is resistant to heat.
option A is correct

Explanation

Microwaves are used in the following applications:

1. Satellite communications
2. Radar communications
3. Analysis of atomic and molecular structure
4. Cooking in microwave ovens

Multiple choice physics pressure in fluids and atmospheric pressure pressure in air introduction to atmospheric pressure pressure exerted by air devices to measure pressure

Cooking is done fast in pressure cooker because

  1. The boiling point of water is lowered

  2. The boiling point of water is increased

  3. More pressure is the cooker cooks the food at 100C

  4. The boiling point remains the same but more steam cooks the food
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In a pressure cooker, as the pressure inside increases with time, the boiling point of water increases and hence is able to cook fast.

Multiple choice evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

Cooking food by covering, is the method to save _________.

  1. LPG

  2. CNG

  3. BNG

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Covering pans keeps the heat in the pan, cooking the food. 


I’ve seen estimates that covered pans consume less than half the energy of uncovered ones, so this is a huge saving both in the amount of LPG used and the heat released in the cabin is used for cooking the food faster.

Hence the option A is correct.

Multiple choice evs experiments with water water and its types hard and soft water what floats - what sinks

 What happens on adding salt to the water in which eggs are boiled?  

  1. Egg will take more time to cook

  2. Egg will start floating on water

  3. Egg will cook faster

  4. Egg will sink in water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Adding salt to water increases the boiling point of the solution (boiling point elevation). Higher temperature water cooks the egg faster.

Multiple choice chemistry metals physical properties of metals and non-metals some physical properties of metals general characteristics and uses of metals

Aluminium foils are used for:

  1. wrapping chocolates and food stuff

  2. to prepare hydrogen
  3. both $A$ and $B$

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Aluminium foils are impermeable to oxygen and water; thus are used for wrapping chocolates and foodstuff. 


It can be used for the preparation of hydrogen using the reaction of aluminium foil with a sodium hydroxide solution.


$2Al + 2NaOH + 6H _2O \rightarrow  2Na[Al(OH) _4] + 3H _2\uparrow$


Hence, the correct option is $\text{C}$

Multiple choice commercial applications treasure under the ground conservation of mineral resources distribution and conservation of mineral resources indian mineral and power resources

Which one of the following practices will NOT conserve LPG in your kitchen?

  1. Soaking the dal for some time before cooking it.

  2. Cooking food in a pressure cooker.

  3. Keeping the vegetables chopped before lighting the gas for cooking.

  4. Cooking food in an open pan kept on low flame.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cooking food in an open pan kept on low flame will not conserve LPG in your kitchen.

Multiple choice

Cooking uses about what percent of global energy?

  1. 1%

  2. 2%

  3. 4%

  4. 8%
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Estimates regarding global energy consumption for cooking vary, but 8 percent is a commonly cited figure in environmental science curricula regarding household energy use in developing regions. Lower percentages like 1 or 2 percent typically underestimate the reliance on biomass for cooking.

Multiple choice

No chemical reactions occur during cooking

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cooking involves numerous chemical reactions, such as the Maillard reaction (browning of meats), caramelization of sugars, and denaturation of proteins.

Multiple choice

Which of these terms best describes what happens to protein when it is cooked?

  1. Denaturation and gelatinisation.

  2. Coagulation and radiation.

  3. Convection and aeration.

  4. Denaturation and coagulation.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

When proteins are heated during cooking, their chemical structure unfolds in a process called denaturation. Following this, the unfolded protein chains bond together to form a solid or semi-solid structure, which is known as coagulation. Gelatinisation refers to starch, while convection and radiation are methods of heat transfer.

Multiple choice

Cooking causes protein in foods to gelatinise and thicken food.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Gelatinisation is a process that occurs when starch granules are heated in a liquid, causing them to swell and thicken the mixture. Proteins, on the other hand, undergo denaturation and coagulation when cooked. Therefore, the statement is false because gelatinisation is specific to carbohydrates, not proteins.
