Answer:
38 cal. Explanation: The key to this problem lies in the value of the specific heat of iron. ciron=0.108 cal g−1∘C−1.
Explanation:
Answer:
b. temperature difference
Answer:
The both refer to the same term.
Explanation:
The heat of neutralization also called the enthalpy of neutralization. It is the heat evolved or the enthalpy change when one equivalent of acid reacts with one equivalent of a base under standard conditions to form salt and water only.
Answer:
It will increase the kinetic energy of gas particles and hence gas will expand.
Explanation:
According to law, there is direct relationship between temperature (thermal energy) of gas and it's volume. When the pressure of gas is held constant and it's temperature increases then the volume of gas also gets increases.
When the temperature ( thermal energy) of gas increases then the kinetic energy of particles of gas also gets increases due to which particles start to collide with the wall of container and with themselves as well which in turn causes gas to expand.
A. Protons and Neutrons will get u the atomic mass.
