Relating Heat, Temperature Change, and Heat Capacity
(a) How much heat is needed to warm 250 g of water (about 1 cup) from 22 °C (about room temperature) to 98 °C (near its boiling point)?
b) What is the molar heat capacity of water?
(a) Large beds of rocks are used in some solar-heated homes to store heat. Assume that the specific heat of the rocks is 0.82 J/g-K. Calculate the quantity of heat absorbed by 50.0 kg of rocks if their temperature increases by 12.0 °C.
(b) What temperature change would these rocks undergo if they emitted 450 kJ of heat?
Week 2: • Activity along mid-ocean ridges: o Deep ocean environments exist where ridges of tectonic plates exist § Newly made rock continuously being regenerated from magma underneath, solidified immediately by cold water § Geologic, seismic environments § “Chimneys”...
