We understand 'temperature' as a measure of the 'hotness' or 'coldness' of a body. Which of the following quantities changes with a change in temperature?
Arrange the following in the order of decreasing temperature:
Which of the following statements is/are correct?
1. Heat flows from the cold body to the hot body.
2. Temperature is a measure of hotness or coldness.
3. Thermometer is used to measure temperature.
A hot body at temperature θ1 is mixed with a cold body at temperature θ2 both having the same heat capacity, such that the rise in temperature of the cold body is equal to the fall in temperature of the hot body. The resultant temperature θ is equal to
A hot body at temperature θ1 is mixed with a cold body at temperature θ2. The fall in temperature of the hot body is equal to the rise in temperature of the cold body. Then find the resultant temperature.
