If it takes 526 j of energy to warm 7.40g of water by 17 degrees celsius, how much energy would be needed to warm 7.40g of water by 55 degrees celsius?

Heat required = 1702 J

Explanation:

The amount of heat energy (Q) required to raise the temperature of water of mass (m) is given as:

where c = specific heat capacity

ΔT =change in temperature

It is given that:

When ΔT = 17 C, Q = 526 J and m = 7.40 g

i.e.

The amount of heat required to increase the temperature of 7.40 g water by 55 C would be:

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
