Weekly Quiz Competition

Question 1
1 / -0

The direction of the flow of heat depends upon

A
quantity of heat in a body

B
temperature difference

C
both 1 and 2

D
none of these
Question 2
1 / -0

What is the normal temperature of a human body on Fahrenheit scale?

A
36.8^o

B
63.8^o

C
98.6^o

D
95.3^o
Question 3
1 / -0

Two bodies A and B are at the same temperature (50^oC).They are placed in contact. The final result will be

A
temperature of A becomes 100^oC

B
temperature of B becomes 100^oC

C
temperature of both A and B becomes 100^oC

D
no change in temperature
Question 4
1 / -0

The quantity of heat required to heat a substance depends upon

A
its mass

B
rise in temperature

C
nature of substance

D
all of these
Question 5
1 / -0

The quantity of heat required to raise the temperature of 1 gm of substance through 1^oC is called

A
calorie

B
specific heat

C
latent heat

D
water equivalent

Solution

The specific heat of a substance is the number of calories needed to raise the temperature of one gram by 1^oC. Because one degree on the Celsius scale is equal to one Kelvin, specific heats in the metric system can be reported in units of either cal/g-^oC or cal/g-K.
Question 6
1 / -0

The branch of physics, which deals with the study and measurement of heat is called

A
pyrometry

B
calorimetry

C
thermometry

D
astrophysics
Question 7
1 / -0

The process in which heat flows from one end of the body to other in the direction of fall of temperature without actual movement of the particles is called

A
convection

B
conduction

C
radiation

D
none of these
Question 8
1 / -0

What is 0^oC on a Kelvin scale?

A
273 K

B
- 273 K

C
186.5 K

D
- 186.5 K

Solution

We know,

Temperature in Kelvin = Temperature in °C + 273

Putting the temperature in °C as zero, we get temperature in kelvin as 273 K.
Question 9
1 / -0

Transfer of heat in liquid and gases is primarily by

A
conduction

B
convection

C
radiation

D
none of these
