By what factor does the gas temperature change if the volume is doubled and the pressure is tripled?

Explanation:

Since, for ideal gases the temperature is in direct relation to the volume and the pressure, you can predict that if the volume is doubled and the pressure is tripled the effect on the temperature will be 3 × 2 = 6 times.

You can prove it using the combined law of gases:

Where the letters P denote absolute pressures, the letters T denote temperature measured in absolute scale, and the letters V denote volume.

The changes given may be written it this way:

Then, you can write T₂ in terms of the other variables:

Cancel the common factors P₁ and V₁

Which proves that the final temperature is 6 times the initial temperature.

b) mutualism

hope this : )

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
