Question

Calculate the amount of heat required to raise the
temperature of 140grams of water from 16°C to 90°C
. The specific heat of water is 4.18J/g ° C.

Answer 1

Answer:

43.1 kJ

Explanation:

Q=mCT, where Q is the energy, m is the mass, C is the specific heat, and T is the temperature change.

Q = (140g)*((4.16 J/(g*C))*(90C - 16C) = 43098 J, or 43.1 kJ with 3 sig figs
