How much energy must be added to a 2-kg piece of wood with a specific heat of 1760 JkgoC to increase its temperature from 10oC to 50oC?

Answer 1

140,800 j

Answer 2

The formula to calculate the energy required is Q = mcΔT, where Q is the energy, m is the mass (2kg), c is the specific heat (1760 J/kg°C), and ΔT is the change in temperature (50-10=40°C). Plugging in the values, we get Q = 2kg * 1760 J/kg°C * 40°C = 140,800 Joules. So, 140,800 Joules of energy must be added to increase the temperature of the wood by 40°C.
