The specific heat capacity of methane gas is 2.20 j/g-k. How many joules of heat are needed to raise the temperature of 5.00 g of methane from 36.0°c to 75.0°c?

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
