Question

Which block has the highest thermal capacity if same heat is applied but temperature rise is different?

Choices

Choice (4) Response
a.
Temperature rise is 6℃

Temperature rise is 6℃

This image is of 6℃.

b.
Temperature rise is 18℃

Temperature rise is 18℃

This image is of 18℃.

c.
Temperature rise is 3℃

Temperature rise is 3℃

This image is of 3℃.

d.
Temperature rise is 9℃

Temperature rise is 9℃

This image is of 9℃.

Answer

c.

Explanation

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. ”

Thermalcapacity=heataddedresultingtemperature

Then we can write block of 30 C rising temperature has lowest rising temperature thus it has the highest thermal capacity.

Question

The weights of four objects is measured. Which object seems to be lightest?

Comparing the weights of four objects 1, 2, 3 and 4.

Comparing the weights of four objects 1, 2, 3 and 4.

In figure three positions of balance are shown in those comparisons of four objects are shown.

Choices

Choice (4) Response
a.

Object 3

b.

Object 1

c.

Object 4

d.

Object 2

Answer

c.

Explanation

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
