Ahot metal plate at 150°c has been placed in air at room temperature. which event would most likely take place over the next few minutes?
a. molecules in both the metal and the surrounding air will start moving at lower speeds.
b. molecules in both the metal and the surrounding air will start moving at higher speeds.
c. the air molecules that are surrounding the metal will slow down, and the molecules in the metal will speed up.
d. the air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

The answer is D.

Explanation:

The room temperature is 25 °C. The temperature of metal plate is 150 °C. The metal atoms are vibrating constantly and the air molecules are also moving around. As the heat is always transferred from a body at higher temperature to a lower one. So, the heat energy will be transferred from the metal plate to the air molecules. As a result of which, the velocity at which the metal atoms were vibrating at first will now go on slowing down while the velocity of air molecules will increase than it was before.

D) The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

This is the correct answer on ed-genuity, hope this helps! :)

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
