Multiple choice evs - i methods of preserving food food spoilage and food preservation food poisoning and food preservation methods food spoilage, adulteration and preservation

The temperature inside your fridge should be

  1. $10^oc$
  2. $4^oc$
  3. $0^oc$
  4. $-2^oc$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The temperature range between 1 to 4 degrees Celsius is an ideal balance between the temperature required to stop/avoid microbial growth and not freeze the food that is to be preserved. 
  • At 0 or -2 degrees Celsius the microbial growth is stopped but the food gets frozen whereas 10 degrees Celsius won't stop microbial growth. 
    Hence, correct option is B.
Multiple choice evs - i methods of preserving food food spoilage and food preservation food poisoning and food preservation methods food spoilage, adulteration and preservation

Temperature in deep freezers for preserving food articles is

  1. 0$^\circ$C
  2. - 4$^\circ$C
  3. - 10$^\circ$C
  4. - 18$^\circ$C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Food stored at or below −18 °C (0 °F) is safe to avoid bacterial growth. Most household freezers maintain temperatures from −23 to −18 °C.

Temperature for UHT of milk is

  1. 95$^0$C for 10 seconds
  2. 110$^0$C for ten seconds
  3. 132$^0$C for one second
  4. 132$^0$C for ten seconds
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ultra-High Temperature (UHT) processing of milk typically involves heating it to approximately 132-140 degrees Celsius for a very short duration, usually 1 to 2 seconds, to ensure sterilization.

Multiple choice zoology bioenergy biogas environmental use of microorganism microbes in waste treatment and biogas

Temperature suitable for biogas production is

  1. $35^o-40^o$C
  2. $20^o-25^o$C
  3. $30^o-35^o$C
  4. $40^o-44^o$C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Biogas production occurs by the action of anaerobic bacteria on waste materials or raw materials. The reactions are made to occur in specially designed large sized tanks called digesters. The bacteria that decompose  the raw materials and produce biogas can be thermophilic if they survive at a higher temperature or mesophilic if they survive at a moderate temperature. Mesophilic bacteria are active at an optimum temperature of 35° - 40°C and thermophilic bacteria are active at an optimum temperature of 50° - 55°C . 
Hence, option A matches the correct temperature suitable for biogas production.
So, the correct answer is '35° - 40°C'.
Multiple choice physics temperature and heat application of various thermometric scales different types of thermometers measuring temperature

To mark a temperature scale on a thermometer, standard temperatures knows as fixed points are needed.
Which of these is a fixed point on the Celsius scale?

  1. room temperature

  2. the temperature inside a freezer

  3. the temperature of pure melting ice

  4. the temperature of pure warm water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

To define the Celsius temperature scale two "reliable" temperatures are used. These are, the melting point of pure ice, which gives us the lower fixed point of the scale and the boiling point of pure water (at atmospheric pressure) which gives us the upper fixed point.

Multiple choice physics measurement and effects of heat application of various thermometric scales different types of thermometers measuring temperature

The range of clinical thermometer is

  1. $37^{o}C$ to $42^{o}C$
  2. $95^{o}F$ to $110^{o}F$
  3. $90^{o}F$ to $112^{o}F$
  4. $95^{o}C$ to $104^{o}C$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The clinical thermometer is a specially designed thermometer to measure the body temperature. The range of a clinical thermometer is centred around the human body temperature around $37^oC \ to \ 42^oC$.

Multiple choice geography life in tropical and subtropical regions life in the ganga - brahmaputra basin drainage system in brazil human environment interactions - the tropical and the subtropical region

What is the average annual temperature in the Amazon basin?

  1. $15^0C-25^0C$
  2. $20^0C-25^0C$
  3. $25^0C-30^0C$
  4. $35^0C-55^0C$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The Amazon Basin stretches directly on the equator and is characterized by a hot and wet climate throughout the year. Both day and nights are almost equally hot and humid. The skin feels sticky. It rains almost every day, that too without much warning. The day temperatures are high with very high humidity. At night the temperature goes down but the humidity remains high. The average annual temperature in the Amazon basin is 25 degrees Celcius to 30 degrees Celcius. 
Multiple choice physics life cycle of stars evolution and end stages of stars the stars stars

At approximately what temperature can helium fusion occur? 

  1. 100,000 K

  2. 1 million K

  3. 100 million K

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

Helium fusion (the triple-alpha process) requires significantly higher temperatures than hydrogen fusion to overcome the increased electrostatic repulsion of helium nuclei. This typically occurs at temperatures around 100 million Kelvin.

Multiple choice geography agriculture in india - ii : food crops pulses cultivation in india production of agricultural crops food crops in india

Production of rice requires an average temperature of about __________.

  1. $21^\circ$C
  2. $22^\circ$C
  3. $24^\circ$C
  4. $28^\circ$C
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Rice is a tropical crop and grown where the average temperature during the growing season is between 20°C and 27°C. ADVERTISEMENTS: Abundant sunshine is essential during its four months of growth. The minimum temperature should not go below 15°C as germination cannot take place below that temperature.

Multiple choice biology concept of life theories of the origin of life origin of life the origin of cells and cell division

At the times of origin of life, the structure temperature of earth was :

  1. $100^o C $
  2. $50-60^o C $
  3. $85-40^o C $
  4. $10-15^o C $
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Scientific consensus regarding the early Earth's environment suggests that the temperature was significantly lower than the boiling point of water, often estimated in the range of 50 to 60 degrees Celsius, which allowed for the formation of organic compounds.
