Temperature Concepts

On both the scales, the number of divisions are 100 and each calibrated line differs by 1⁰.

Yes, the temperature graduations of a thermometer may be inadequately calibrated, which is an instrumental error.

The maximum temperature that a solar cooker can attain is 100° - 140°C. At this temperature, food can be cooked.

If the temperature difference between water at the surface and water at a depth of up to 2 km is 20 K, then these plants work.

Holding period in an autoclave is 121^oC for 12 min at 15 lbs pressure or 134^oC at 30 lbs pressure for 3 minutes.

Camel can increase the body temperature by almost 5 degrees.

The time required to cool down a liquid is directly proportional to the heat to be extracted. The evaporation produces cooling effect. More is the evaporation rate, more easily the liquid becomes cool.

98.4^o F - 99^o F is normal range.

Psychrophiles are microorganisms which are capable to grow below 15^oC to 0^oC.

This is the correct option. The common unit of measuring temperature is degree Celsius. The laboratory thermometers that are used for performing science experiments are all calibrated in degree Celsius.

Normal human body temperature is approximately 98.4°F (37°C) when measured orally. This value represents the average baseline temperature for a healthy adult at rest. Individual variation exists, with temperatures ranging from about 97°F to 99°F considered normal.

The Sun's photosphere (visible surface) has a temperature of approximately 5,500°C or 5,778 K. Option B (6000°C) is the closest approximation given. The other options are either too low or too high. This is standard astronomical data about our Sun.

The World Health Organization states that cooking poultry to 70°C (158°F) ensures that the avian influenza virus is completely destroyed. At 100°C (boiling point of water), the virus is definitely eliminated. Lower temperatures like 60°C or 70°C may not be sufficient to guarantee complete inactivation of the virus in all parts of the food.
