Answer:

2682.9J is the heat absorbed by the wood

Explanation:

To find the heat absorbed for a material we must use the equation:

Q = S*m*ΔT

Where Q is heat absorbed in Joules

S is specific heat of the material = 1.76J/g°C for wood

m is the mass of the material = 41.2g

ΔT is change in temperature = 65.1°C - 28.1°C = 37.0°C

Replacing:

Q = 1.76J/g°C*41.2g*37.0°C

Q = 2682.9J is the heat absorbed by the wood
