Which two fossil fuels were formed from the remains of marine organisms? petroleum and natural gas petroleum and coal coal and natural gas

Fossil fuels are non-renewable sources of energy i.e. they cannot be regenerated at a sufficient rate and are prone to run out over a period of time.

Petroleum, Coal and Natural gas are all fossil fuels. However, petroleum and natural gas were formed from the remains of marine organisms. These are essentially hydrocarbons composed mainly of carbon and hydrogen.

Ans: a) petroleum and natural gas

The answer is PETROLEUM and NATURAL GAS

Explanation:

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
