Question 1
4 / -1

Bond angle in H₂O is 104.5 °; then bond in Cl₂O should be -

A
104.5 °

B
101 °

C
109 °28'

D
110.8 °

Solution

Due to large size of Cl, the bond angle will be greater than 109 °28'.
Question 2
4 / -1

Which of the following statements is true? ,

The entropy of the universe–

A
Increases and tends towards maximum value

B
Decreases and tends to zero

C
Remains constant

D

Solution

Second law of thermodynamics states the entropy of the Universe increases and bends towards maximum value.
Question 3
4 / -1

The stopping potential (V₀) -

A
Depends upon the angle of incident light

B
Depends upon the intensity of incident light

C
Depends upon the surface nature of the substance

D
Is independent of the intensity of the incident light

Solution

Stopping potential is independent of the intensity of incident light. Stopping potential depends on frequency of incident light greater than threshold frequency.
Question 4
4 / -1

A metal cube is placed in an empty vessel. When water is filled in the vessel so that the cube is just immersed in the water, the force on the bottom of the vessel in contact with the cube

A
will increase

B
will decrease

C
will remain the same

D
will become zero

Solution

The force on the bottom of the vessel in contact with the cube, leading to no actual displacement of liquid. Also, the cube is just immersed. Hence, the force remains same.
