The specific heat of copper is 0.40 joules/ g °c. How much heat is needed in joules to change the temperature of a 55 gram substance from 20.0 ° C to 74.0 °C ? c=.40 J/g °C.

I need it worked out pleaseee

Answer : The amount of heat needed is, 1188 J

Explanation :

Formula used :

where,

q = heat needed = ?

m = mass of copper = 55 g

c = specific heat capacity of copper =

= initial temperature =

= final temperature =

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

Thus, the amount of heat needed is, 1188 J

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
