Aansi wants energy on a sound wave to be carried more quickly through a metal medium. which could she do? decrease the temperature increase the temperature use a gas medium instead use a liquid medium instead

The correct option is INCREASE THE TEMPERATURE. This is because, temperature affects the speed of sound. Heat is a form of kinetic energy and particles with high kinetic energy are able to move faster than those with low kinetic energy. Increasing the temperature will speeds up the motion of the molecules, which will in turn speed up the vibration of the molecules and enable them to travel faster.

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
