Asteel plaque is attached to a block of wood. the steel and the wood have the same mass. after the steel plaque and the wooden block were left outside in the sun for a period of time, both the steel and the wood had increased in temperature, but the steel had a higher temperature than the wood. it’s possible that the steel plaque had a higher temperature than the wooden block because its surroundings. if the steel and the wood received the same amount of energy from the sun, then the specific heat capacity of the steel must the specific heat capacity of the wood. choices for blank 1: absorbed more energy from --released more energy to--way better insulated from choices for blank 2: equal to --less then

General Remark

The amount of energy transferred from the sun to the wood and steel is determined by m*c*deltaT. [So far, you really only have 2 choices for heat energy transfer. One is the one you are using m*c*deltaT and the other one is Mass * heat. This latter is for phase changes].

Solution

What causes the temperature to be higher in one part of the sample than on the other part? If they both receive the same amount of heat (as in getting their energy from the sun) then why does one deltaT exceed the other? Look around at the parts of the formula. That's very important in science. The mass (m) is not going to affect the different temperatures. The mass is the same in both cases.

It won't be deltaT either. DeltaT has already done it's job. It's recorded that there is a temperature difference. Steel has a larger deltaT than the wood.

What's left?

It must be the c. What are the units on c? If you check it out it is joules / (oC * grams) or something that means grams and deltaT. So c must be lower than steel than for wood. Why? Because it takes less energy to heat up the steel. Small c means large deltaT if the temperature is greater in the iron.

Answers

Blank One absorbed more energy from. c is small.

Blank Two Less than.

This is an extremely important question to get a handle on. More and Less are very important key words in Science.
