The amount of heat required to raise the temperature of __________ water through one degree is called kilojoules.
A. 1 g
B. 10 g
C. 100 g
D. 1000 g
Answer: Option D
Solution (By Examveda Team)
The amount of heat required to raise the temperature of 1000 g (or 1 kg) of water through one degree Celsius is called a kilojoule.This is because the specific heat capacity of water is approximately 4.186 kJ/kg°C, meaning that 1 kg of water requires about 4.186 kJ to increase its temperature by 1°C.
The smaller masses such as 1 g, 10 g, or 100 g would require proportionally less heat energy.
