When a metal ring having some gap is heated
(a) length of gap increases
(b) radius of the ring decreases
(c) the angle substanded by the gap at the centre remains same
(d) length of gap decreases

When a metal ring having some gap is heated a) length of gap increases b) radius of the ring decreases c) the angle subtended by the gap at the centre remains same d) length of gap decreases

When a liquid in a vessel is heated its level (a) will increase (b) may increase or decreases ( c) will decrease (d) may remains same

A long metal rod is bent to form a ring with a small gap if this is heated, will this gap increase or decrease?

A long metal rod is bent to form a ring with a small gap if this is heated, will this gap increase or decrease?

A metal rod is shaped into a ring with a small gap. If this is heated, (i) the length of the rod will increase (ii) the gap will decrease (iii) the gap will increase (iv) the diameter gof the ring will increase in the same ratio as the blength of the rod

The radius of a wire is decreased to one third. If volume remains the same, the length will become

As the temperature is increased, the period of a pendulum a) Increases as its effective length increases even through its centre of mass still remains at the centre of the bob. b) decreases as its effective length increases even though its centre of mass still remains at the centre of the bob. c) Increases as its effective length increases due to shifting of centre of mass below the centre of the bob. d) decreases as its effective length remains same but the centre of mass shifts above the centre of the bob.

A small ring having small gap is shown in figure on heating what will happen to size of gap.
