Even when shut down after a period of normal use, a large commercial nuclear reactor transfers thermal energy at the rate of 150mw by the radio active decay of fission products. this heat transfer causes a rapid increase in temperature if the cooling system fails. (1 watt = 1 joule or 1w = 1j/s and 1mw = 1megawatt)calculate the rate of temperature increase in degrees celsius per second (°c/s) if the mass of the reactor core is 1.60×105kg and it has an average specific heat of 0.3349 kj/kg°c.

The temperature of the core raises by every second.

Explanation:

Since the average specific heat of the reactor core is 0.3349 kJ/kgC

It means that we require 0.3349 kJ of heat to raise the temperature of 1 kg of core material by 1 degree Celsius

Thus reactor core whose mass is will require

energy to raise it's temperature by 1 degree Celsius in 1 second

Hence by the concept of proportionately we can infer 150 MW of power will increase the temperature by

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
