3- The state of the substance (on change in temperature)

-5º C 20º C
Controlled variable:
Mass of a substance & Heat quantity
Independent variable:

Physical state of the substance
Dependent variable:

The amount of change in temperature
Observation The elevation of the temperature of ice (solid) is greater
than its elevation of water (liquid)
Conclusion The amount of change in temperature of equal masses of

different states of same substance varies when this
substance gains / loses the same quantity of heat
Explanation

The elevation of the temperature of a mass of ice is greater
than its elevation of the same mass of water when they gain

same quantity of heat as

The specific heat of ice is less than that of water
