Question

Two liquids A and B have specific heat capacities 2.5 Jg-1 0C
-1
and 3.2 Jg-1 0C
respectively.
(i) Which liquid is a good conductor of heat? Why?
(ii) Which liquid is more suitable as a liquid in radiators for cooling?

Answer 1

I)liquid a is gud conductor of heat as it takes less heat to rise temp by 10c as compared to liquid b

ii)liquid b as it will absorb more heat compared to liquid a for same rise in temp..

hope it helps.....

Answer 2

Answer:

i) Since it takes less energy to raise a liquid's temperature by one degree, it is said to have a specific heat capacity of 2.5.

ii) Since liquids with a high specific heat are employed as coolants, a liquid with a specific heat of 3.2 is more suited for cooling.

Explanation:

What is Specific Heat ?

Since it takes less energy to raise a liquid's temperature by one degree, it is said to have a specific heat capacity of 2.5.

Since liquids with a high specific heat are employed as coolants, a liquid with a specific heat of 3.2 is more suited for cooling.

The amount of heat needed to increase a substance's temperature by one degree Celsius in one gramme, also known as specific heat. Typically, calories or joules per gramme per degree Celsius are used as the units of specific heat. For instance, water has a specific heat of 1 calorie (or 4.186 joules) per gramme per degree Celsius.

Water has a high specific heat, which implies that adding heat to raise its temperature uses up a lot of energy. By doing this, the environment's temperature is kept from being excessively hot or cold. Humans contain around 66% water, therefore this feature of water also aids in our ability to control body temperature.
