Hello, so in this question you'll be using energy conservation.
00:05
So once you put the ice in the water, we're gonna have the water losing heat to the ice.
00:12
So we can say the heat lost by the water is going to be equal to the heat gained by the ice.
00:17
So for the water we have the mass of the water, specific capacity.
00:22
Oops, one second.
00:23
We have changing temperature of the water.
00:27
For the ice, we're gonna have the number of moles of ice so here we're gonna say it's gonna be like liquid ice at zero degrees.
00:37
And then here we're gonna have the heat of fusion.
00:46
So we can say times the heat of fusion.
00:54
So here we can find the number of moles of ice.
00:58
We're gonna have mass of water, specific capacity of water times changing temperature, divided by the heat of fusion.
01:11
Mass of the water is is so here because the specific capacity is given in joule per grams, we just maintain the grams.
01:21
So we're gonna have the mass of water to be 25.
01:28
Specific heat capacity is 4 .18...
