Question

1. Define heat.
2. What is the condition of 'thermal equilibrium?
3. Define one calorie of heat.​

Answer 1

Explanation:

1.- heat

is a form of energy that dissipate through the power supply .

given by

Henry

joules law of heating effect which is

$h = i {} {}^{2} rt$

2.-

all the forces acted for thermal equilibrium shud be zero.

3.-

1kcalorie heat is produced in 1 joule of heat.

Answer 2

Answers :-

1.Heat

•Heat is a form of energy that flows from a body at higher temperature to a body at lower temperature.

•SI unit is Joules

•Net heat lost = Net heat gain

•It is a thermal energy

•Heat is ampunt of energy of the system.

2.Thermal equilibrium.

Condition :- The forces must be zero.

About it :-

•Two bodies are at the same temperature then they sre said to be in thermal equilibrium.

•The temperature of two bodies is always same in thermal equilibrium.

•Temperature is the measure of thermal equilibrium.

3. I joule of heat required to burn is called as I calorie .
