Calculate the specific heat capacity of a piece of wood if 150.0g of the wood absorbs 67,000 joules of heat, and it’s temperatur
svet-max [94.6K]

Answer:

17.8 J/g^{\circ}C

Explanation:

When a certain amount of substance is supplied with a certain amount of energy Q, the temperature of the substance increases according to the equation

Q=mC\Delta T

where

m is the mass of the substance

C is the specific heat capacity

\Delta T is the change in temperature

In this problem:

m = 150.0 g is the mass of wood

Q=67,000 J is the amount of energy supplied to the wood

\Delta T=55-30=25^{\circ}C is the increase in temperature of the substance

Therefore, the specific heat capacity is:

C=\frac{Q}{m\Delta T}=\frac{67,000}{(150.0)(25)}=17.8 J/g^{\circ}C
