Hello students.
00:01
So, this question has two parts.
00:03
In the first part, we have 10 moles of water and we have to find the heat required to raise its temperature from 0 degree celsius to 100 degree celsius.
00:19
So, the mass of 10 moles of water is going to be, so we know that the mass of 1 mole of water is 18 into 10 grams, that is 180 grams.
00:34
So, the formula to calculate q, heat required is mass into specific heat of water into the delta t.
00:42
So, the mass we have calculated as 180 grams, the specific heat is given as 2 .09 joule per gram degree celsius and the temperature difference is 100 minus 0 degree celsius.
00:56
So, the heat required is 37620 joules, that is equals to 37 .62 kilojoules of heat are required...
