(e) Geothermal power stations pump water through heated rocks. The temperature of the water increases from 20 °C to its boiling point of 100°C
Calculate the change in thermal energy when the mass of water heated is 150 kg
Specific heat capacity = 4 200 J/kg °C

In order to calculate the amount of heat transferred you must know the __ and specific heat of the material, as well as the change in temperature. a. volume b. density c. mass d. enthalpy

City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city a was 8â° c more than 3 times the temperature of city b. the temperature of city a minus twice the temperature of city b was â’3â° c. what was the temperature of city a and city b on that day? city a was 5â° c, and city b was 4â° c. city a was 3â° c, and city b was â’1â° c. city a was 8â° c, and city b was â’3â° c. city a was 5â° c, and city b was â’5â° c.

Which of the following elements would you expect to have the lowest ionization energy value? fluorine, lithium, neon, nitrogen
