900J
Explanation:
Given parameters:
Specific heat of the aluminium = 900Jkg⁻¹K⁻¹
Mass of aluminium = 0.5kg
temperature change = 2K
Unknown:
Quantity of heat = ?
Solution:
The quantity of heat a body absorbs to cause a change in temperature is given as:
H = mcΘ
H is the quantity of heat
m is the mass of the substance
c is the specific heat capacity
Θ is the temperature change
H = 0.5 x 2 x 900 = 900J
