1.) What is the equation for calculating changes in thermal energy?
2..) What is the equation for calculating specific heat? Hint: you need to rearrange the equation you just wrote down?
3.) How much energy must be transferred as heat to the 420 kg of water in the bathtub in order to raise the water’s temperature from 25C to 37C?
4.) How would you express the answer you just got in kj?
5.) How world you express the kj number in scientific notation?
6.) A Vanadium bolt gives up 1124 J of energy as its temperature drops 25 K. If the bolt’s mass is 0.093 kg, what is its specific heat? Hint: you will need to rearrange the equation to solve for specific heat ©.
