Potential energy or chemical potential energy is used to Cook food which is then converted into thermal energy. The type of energy used also depends upon the type of cooking appliances used.
For e.g. stove convert potential energy to thermal energy.
The first law of thermodynamics is expresses by
D. ΔU=Q-W
which means change in internal energy of system = Heat added to system minus work done by the system
All are expressed in Joules.
This law is based on principle of conservation of energy.

Answer:
the weight of the object, the force of gravity acting on said object, and the mass of the object are needed for Newton's second law of motion.
Answer: Average acceleration is -2.407 
Explanation:
Average acceleration is equal to change in velocity divided by time taken
therefore, 
=>
