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 temperature changes from 30c to 55c

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

where

m is the mass of the substance

C is the specific heat capacity

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

is the increase in temperature of the substance

Therefore, the specific heat capacity is:

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
