The current leading into an electromagnet with a strength of 800 ampere-turns is reduced by the electric company from 20 amp to 10 amp. What can you change to keep the strength of the electromagnet constant? Show all your calculations.

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.
