The specific heat of silver is 0.234 J/(g·K). Calculate the amount of energy that is needed to

raise the temperature of 175 g of silver from 22.5°C

to 40.0°C.

Because a model would make the investigation easier to understand

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.
