Calculate the energy released when a 28.9 gram piece of paper is cooled from its melting point of 1083 degrees celsius to 25.0 degrees celsius. the specific heat of copper is .385 j/g celsius.

Answer : The energy released will be, -11771.837 J

Solution :

Formula used :

where,

Q = heat released = ?

m = mass of copper = 28.9 g

c = specific heat of copper =      

= final temperature =

= initial temperature =

Now put all the given values in the above formula, we get :

Therefore, the energy released will be, -11771.837 J

i do not get it   at all

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
