Assuming that the heat capacities don't change with temperature, how much energy in kilojoules is needed to heat 7.70 g of Hg from a temperature of 58 to 51

Answer : The energy needed is,

Explanation :

Formula used :

where,

q = heat needed = ?

m = mass = 7.70 g

c = specific heat =

= final temperature =

= initial temperature =

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

Thus, the energy needed is,

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire
