Question

How much heat, in joules, is required to raise the temperature of 8.2 g of

water by 3.32°C? (Specific heat of water is 4.18 J/gºC) Your answer should be
rounded to one number after the decimal and does not need units; Example
0.1*

Answer 1

113.8 J.

Step-by-step explanation:

The following data were obtained from the question:

Mass (M) = 8.2 g

Change in temperature (ΔT) = 3.32 °C

Specific heat capacity (C) = 4.18 J/gºC

Heat required (Q) =..?

The heat required to raise the temperature of the water by 3.32 °C

can be obtained as follow:

Q = MCΔT

Q = 8.2 × 4.18 × 3.32

Q = 113.8 J

Therefore, the amount of heat required to raise the temperature of the water is 113.8 J.
