Question

At which temperature does water have particles with a greater average kinetic energy than water with a temperature of 30°C?

77°F
95°F
280K
300K

Answer 1

95F

Step-by-step explanation:

First we convert these temperatures into °C:

77°F = 25°C

95°F = 35°C

280K = 6.85°C

300K = 26.85°C

When temperature increases, water molecules have a greater average kinetic energy ans are more likely to collide with each other.

Out of the 4 temperatures, only 95°F (35°C) is of a higher temperature than 30°C. Hence 95°F is the answer.
