If it takes 526 J of energy to warm 7.40g of water by 17 degrees celsius, how much energy would be needed to warm 7.40g of water
2 answers:
Answer:
Heat required = 1702 J
Explanation:
The amount of heat energy (Q) required to raise the temperature of water of mass (m) is given as:
where c = specific heat capacity
ΔT =change in temperature
It is given that:
When ΔT = 17 C, Q = 526 J and m = 7.40 g
i.e.
The amount of heat required to increase the temperature of 7.40 g water by 55 C would be:
