QuestionWhich block has the highest thermal capacity if same heat is applied but temperature rise is different?
Here we show four block. Each of have different value of rise temperature. Now as we know that thermal capacity is a measurable physical quantity which can be define as “The ratio of heat added to an object to the resulting temperature change. ”
Then we can write block of 30 C rising temperature has lowest rising temperature thus it has the highest thermal capacity.

The weights of four objects is measured. Which object seems to be lightest?
Here in above we shows that
In (a) diagram we shows that object 2 is lighter than object 1
In (b) diagram we shows that object 2 is lighter than object 3
So, we can say that object2 is lighter than 1 and 3
But from (c) diagram we can see that object 4 is lighter then object 2
Hence, object 4 is the lightest
