Point a and point b are 50 meters apart. the temperature at point a is 60°c. at point b, it is 55°c. the temperature gradient between the points is . keeping other conditions constant, if the mantle and the crust were closer to each other, the temperature gradient between the two would be .

Given:

Temperature at A = 60 C

Temperature at B = 55 C

To determine:

The temperature gradient

Explanation:

Temperature gradient can be expressed as the variation in temperature from one point to the other

Temperature gradient = ΔT/Δd

= (60-55) C/50 m = 0.1 C/m

Ans: Thus the temperature gradient is 0.1 C/m

0.1 c/m and higher

Explanation:

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
