An automobile engine provides 624 Joules of work to push the pistons. In this process the internal energy changes by -2846 Joules. Calculate q for the engine. This represents the amount of heat that must be carried away by the cooling system. q= Joules
The heat capacity of a substance can be obtained by multiplying its mass by its specific heat. Specific heat is defined as the amount of heat that must be supplied to the unit mass of the substance to raise its temperature by one unit. According to this, indicate the units in which the heat capacity is measured.
