How many joules of heat energy are absorbed when 50.0 grams of water are heated from 50.0°C to 60.0°C?
Ivahew [28]

<u>Answer:</u>

<em>2090 \ j needed to heat the amount of water giving. </em>

<u>Explanation:</u>

To solve this question we first need to know the specific heat of water which is given by <em>4.18 joules</em> Per gram for increasing <em>1° of  temperature</em>. Now since one gram of water name one joules per gram so 2 grams will need <em>twice of 4.18</em> that is 8.36 similarly 50 grams will need 50 \times 4.18 = 209

Now we need to calculate the heat for 10° of change because temperature rises from 50° centigrade to 60° centigrade and difference in degrees

<em>so heat needed is= 209 \times 10 = 2090 \ j</em>
