Tia learns that the temperature of rock in Earth's mantle varies depending on its location. Rock located close to the lithosphere is about 1,000 °C, and rock located close to the outer core is about
3,700 °C.
Tia uses the formula shown below to calculate the amount of heat that needs to be added to a 5-9
piece of rock in order to raise its temperature from 1,000 °C to 3,700 °C. She uses 0.79 J/g °C for
the specific heat of the rock
What is the amount of heat, in joules, that needs to be added to the piece of rock?

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
