Answer: Amount of heat needed = 2884.392 J
Explanation:
The formula for calculating the quantity of heat needed to raise the temperature of a bodyis expressed as
H = mcθ
where
H is the quantity of heat
m is the mass of the body
c is the specific heat capacity of the body
θ is the change in temperature
From he information given,
m = 291 grams
specific heat capacity of silver = 0.240 J/gC
initial temperature = 18.1
Final temperature = 59.4
θ = 59.4 - 18.1 = 41.3
Thus,
H = 291 x 0.240 x 41.3
H = 2884.392 J
Amount of heat needed = 2884.392 J
