Correct option is A
The specific heat is defined as the quantity of heat required to raise the temperature of unit mass of a material by one degree Celsius (or Kelvin). It is an important property in thermodynamics and heat transfer.
Formula:
Q=mcΔTQ = mc\Delta TQ=mcΔT
Where:
QQQ is the heat added,
m is the mass,
c is the specific heat, and
ΔT\Delta TΔT is the change in temperature.
1. Specific Heat:
This is the quantity of heat required to raise the temperature of one unit mass of a substance by one degree Celsius.
2. Thermal Expansion:
Thermal expansion refers to the change in the dimensions of a material when its temperature changes, not the heat required for a temperature change.
3. Temperature Stress:
Temperature stress is the stress developed in a material due to changes in temperature, not the heat required to change the temperature.
4. Heat of Hydration:
Heat of hydration refers to the heat released during the chemical reaction between water and cement, not the heat required to raise the temperature of a material.
