heat

Question 1

formula to convert Celsius to Fahrenheit

Answer 1

Tc-0/100==Tf-32/182

Question 2

linear thermal expansion

Question 3

aerial expansion in terms of beta and alpha

Answer 3

`

Question 4

volume expansion

Question 5

variation of censity with gamma

Question 6

relation between change in length and change in moi of rod

Question 7

equivalent coefficient of linear expansion of 2 rods

Question 8

when 2 rods are joined parallelly and heated what is the angle farmed at centre on bending

Answer 8

[R-(t/2)]theta =L.(1+alpha delta T )
[R+(t/2)theta]=L.(1+alpha2 delta T )

divide 1 by 2 to get R and substitute in any eq to get theta

Question 9

formula for heat in terms of specific heat

Answer 9

q=MS DELTA T

M=given mass

Question 10

Q in terms of Latent heat

Answer 10

Q=ML

Question 11

latent fusion of ice to water

Answer 11

80 cal/grams

Question 12

latent heat of vaporisation of water

Answer 12

500 cal/grams

Question 13

Q in terms of molar specific heat (C)

Answer 13

Q=nC delta T

Question 14

relation between molar specific heat and specific heat (S)

Answer 14

C=M.S

M.=molar mass
S=specific heat
