Ahot glass full of hot water is put into the freezer. the glass breaks because it contracts more than the water as it cools. the reason for this is: a. the glass has a smaller coefficient of linear expansion than the water. b. the water has a larger coefficient of linear expansion than the glass. c. the glass has a larger coefficient of linear expansion than the water. d. the two have equal coefficients of linear expansion.

C.the glass has a larger coefficient of linear expansion than the water.

Explanation:

As we can see that in the given example hot water is poured in the glass beaker and put into the freezer

now when we placed the system into the freezer then in that case the water as well as the glass beaker will start contract.

Now if the rate of contraction of the water is less than the rate of contraction of the beaker then in that case the beaker will not get the sufficient space to fill it.

Due to this the deficiency of space may create the breaking of glass

so here correct answer should be

C.the glass has a larger coefficient of linear expansion than the water.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
