The volume of a fixed amount of a gas vanes directly as the temperatureand as the pressure P. Suppose that V = 120 cm ^ 3 when I = 260 kelvin and P=13 kg cm^ 2 Find the volume when T = 380 kelvin and P=15 kg cm^ 2.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

a
