|
Answer» tion:Question 1: What is heat? What is the S. I. unit of heat?Answer: Heat is a FORM of energy, which when absorbed by a body makes it hot and when extracted from a makes it cold. It is also defined as the total kinetic energy POSSESSED by all the MOLECULES of a body. The S. I. unit of heat is joule/kg kelvin.Question 2: Define the term calorie. How is it related with joule (the SI unit of heat)?Answer: One calorie is the heat required to raise the temperature of 1 g of water from 14.5°C to 15.5°C1 Calorie = 4.2 joule. Question 3: Differentiate between heat and temperature.Answer:Heat Temperature1. It is a form of energy. It is the sensation of hotness and coldness.2. Unit of heat is Joule. Unit of temperature is °C or Kelvin.Question 4: What are other units of heat? Name and define them.Answer: (i) Calorie: It is the quantity of heat required to raise the temperature of 1 GM of water by 1°C (more ACCURATELY the rise in temperature is taken from 14.5°C to 15.5°C).(ii) Kilo calorie: It is the quantity of heat required to raise the temperature of 1 kg of water by 1°C. It is equivalent to 1000 calories.Question 5: How is the heat capacity of a body related to the specific heat capacity of its substance?Answer: Heat capacity of a body = Mass of the body × Specific heat capacity of its substance. |
