Question

Solve the following problems:
a. Equal heat is given to two objects A
and B of mass 1 g. Temperature of A
increases by 3 °C and B by 5 °C.
Which object has more specific heat?
And by what factor?​

Answer 1

Question 1:

Fill in the blanks and rewrite the sentence.

a. The amount of water vapour in air is determined in terms of its ........... .

b. If objects of equal masses are given equal heat, their final temperature will be different. This is due to difference in their ................. .

c. During transformation of liquid phase to solid phase, the latent heat is ............ .

ANSWER:

a. The amount of water vapour in air is determined in terms of its absolute humidity.

b. If objects of equal masses are given equal heat, their final temperature will be different. This is due to difference in their different specific heat capacity.

c. During transformation of liquid phase to solid phase, the latent heat is latent heat of fusion.

Answer 2

Answer:

specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.

By formula-:

Q= mc∆T

or

C= Q/m∆T

where Q is amount of heat added

T is temperature

M is mass

now, two object A and B

then the ratio of specific heats of two object is given as-:

cA/cB= (QA/MA∆TA) of QB/MB∆TB

= CA/CB= QA by MB∆TB/QB by MA∆TA

so, the ans. is

CA/CB= 5/3 or 1.66answer
