the ____ temperature of an object the lower its thermal energy

Answers

the answer is lower. when there’s a lower temperature the molecules will be moving at a lower speed. a lower speed means less thermal energy.

Thermal energy is the average sum of all kinetic energy of all the molecules of gases. The lower the temperature of an object the lower its thermal energy.

What is Thermal energy?

Thermal energy is a energy which is possess by a moving object. It is directly proportional to kinetic energy of the molecules. It is very difficult to find the correct value of kinetic energy so we find average kinetic energy. Which is very easy to calculate as compared to calculating kinetic energy.

Mathematically,

K.E=2/3KT

Where,

K= Boltzmann constant

T is the temperature

Average kinetic energy is directly proportional to temperature. It is not dependent on the type of gases or mass of gases. The lower the temperature of an object the lower its thermal energy.

Therefore, the lower the temperature of an object the lower its thermal energy.

Rust Pipe Co. was established in 1994. Four years later the company went public. At that time, Robert Rust, the original owner, decided to establish two classes of stock. The first represents Class A founders' stock and is entitled to twelve votes per share. The normally traded common stock, designated as Class B, is entitled to one vote per share. In late 2010, Mr. Stone, an investor, was considering purchasing shares in Rust Pipe Co. While he knew the existence of founders shares were not often present in other companies, he decided to buy the shares anyway because of a new technology Rust Pipe had developed to improve the flow of liquids through pipes. Of the 1,900,000 total shares currently outstanding, the original founder's family owns 52,725 shares. What is the percentage of the founder's family votes to Class B votes?
