Question

An aluminum block absorbs 1.0 x 104 J of energy from the Sun when its temperature increases by 5.0 °C. What is the mass of the block?
the specific heat capacity of aluminum is 920

Answer 1

10^4 = 920 * m * 5
m = 10,000 /4,600 kg

Answer 2

Q=1x10^4
c = 9.2 x10^2
△T=5°C

Quantity of heat formula:
Q=mc△T

Rearrange the formula to solve for mass:
m=Q/c△T
m=1x10^4/(9.2x10^2)(5)
m=2.2kg
