The specific heat capacity (c) of a substance is the thermal energy required
to raise one gram of the substance by one degree celsius. the total amount
of thermal energy (q) added to a sample of a substance can be calculated
by multiplying the specific heat capacity (c) by the mass of the sample (m)
and the temperature change (t): q c m t. it takes 125 kilojoules (kj)
of energy to heat a cup of water, increasing its temperature by 1°c. what
is the temperature change in °c of the cup of water after 750 kj of energy
are used? s

Temperature of the same cup of water will rise by 6 °C unless it boils.

.

However, neither nor is given.

Adding to this cup of water of mass rises its temperature by .

In other words,

.

Both and are constant for the same cup of water unless the water boils. It's possible to reuse the value of in the second calculation. Here's how:

.

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.
