What is meant by sensitivity in a thermometer?
A measure of how hot or cold a substance is
the ability to detect and measure a small change in temperature
the time required for thermometric substance to reach the temperature of the surrounding
the even expansion of the liquid with equal increase in temperature
What is meant by heat capacity?
Amount of thermal energy required to change state of a unit mass without change in temperature

amount of thermal energy required to raise the temperature of a unit mass by 1°C
Specific latent heat is given by
mass / thermal energy
thermal energy / mass
thermal energy / (mass X change in temperature)
(mass X change in temperature) / thermal energy
