Thermal energy added to a substance that is not changing state causes the substance’s temperature to
tatyana61 [14]

Answer:

increase

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction. Conductors include metal, steel, aluminum, copper, frying pan, pot, spoon etc.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Hence, thermal energy added to a substance that is not changing state causes the substance’s temperature to increase because it would absorb energy in the form of heat.

Soloha48 [4]

Answer:

It won't change.

-26F=3.33C

Explanation:

The pressure won't change since the system is closed and its volume is the exact same, the only way to change the tanks pressure is to open or pump more gas into or changing the temperature.

- To convert Fahrenheit to Celsius, you need to subtract 32 and divide by 1.8, in the next equation will substitute 26 F.

C=(F-32)\1.8

C=(26-32)\1.8

C=-3.33

I hope you find this information useful and interesting, good luck!
