Answer:
429 J joules of heat are needed to raise the temperature of 5.00 g
Explanation:
given data
specific heat capacity = 2.20 j/g-k
methane = 5.00 g
temperature range = 36.0°c to 75.0°c
to find out
How many joules of heat are needed to raise the temperature of 5.00 g
solution
we will apply here formula for heat that needed to raise the temperature
Q = m × S × Δt ..............................1
m is mass of methane and S is specific heat capacity and Δt is change in temperature
put here value we get
Q = m × S × Δt
Q = 5 × 2.2 × ( 75 - 36 )
Q = 5 × 2.2 × 39
Q = 429 J
so 429 J joules of heat are needed to raise the temperature of 5.00 g
