Temperatures expressed in the kelvin scale are higher than temperatures in the celsius scale. a. 460° b. 200° c. 283° d. 273°

d

Explanation:

Celsius temperatures can be negative while kelvin goes down to absolute zero and doesn’t go any lower, thus no negative numbers

option (D)

Explanation:

The melting point of ice is 0 degree and the boiling point of water is 100 degree on Celsius scale. There are 100 divisions between the melting point and the boiling point.

The melting point of ice is 273 degree and the boiling point of water is 373 degree on Kelvin scale. There are 100 divisions between the melting point and the boiling point.

The relation between the Celsius scale and the Kelvin scale is

So, K = C + 273

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.
