Dear students, specific heat of four metals are given, copper, gold, iron and silver.
00:08
Now, amount of each metal taken is 50 gram.
00:11
Same amount of heat is given to all.
00:14
Then the question is at the same temperature, the question is which metal will reach the lowest temperature? when we give same amount of heat to 50 gram of each of all the metals, all the four metal at the same temperature, which metal will reach the lowest temperature? that means which metal, for which metal the temperature rise is lowest.
00:42
Now you see, let us try to understand what is specific 8.
00:44
Specific unit is zool per gram per degree celsius.
00:47
That means it is the amount of heat required, amount of heat required to raise the temperature of 1 gram of the substance, 1 gram of substance by 1 degree celsius.
01:15
So to raise the temperature by 1 degree celsius for 1 gram of the substance, the amount of heat required that is known as specific heat.
01:24
So now if you see here, in case of iron, we need maximum amount of heat to raise the temperature by 1 degree celsius.
01:33
And in case of gold, it is the minimum...
