So this question says that the specific heat of silver is 0 .24 joules per gram degree celsius.
00:15
So what that means is that for every gram of silver that we want to change by 1 degree celsius, we need to add 0 .024 joules.
00:26
The first question says if we have 150 grams of silver, and we want the temperature change to be 2 from 273 to 2 to 98 and whether these are both kelvin or both celsius doesn't matter as long as they're both in the same unit kelvin or celsius this looks like we are going to use q equals mc delta t and the reason why we're going to use that formula is because it allows us to calculate the amount of heat when using this type of information so now the q is the amount of heat.

That's my x the mass is a hundred and fifty grams.
01:12
The c value is 0 .24.
01:15
And 298 minus 273 is my delta t, which is 25.
01:22
So now if i just take these numbers and plug them all into the calculator, i get my answer.
01:31
And the answer for this would be 900 joules.

The second part of the question asks us for the molar heat capacity...
