Final answer:
The type of gas that follows the gas laws at all conditions of temperature and pressure is an ideal gas. Real gases approach ideal behavior under low pressure and high temperature but deviate under high pressure and low temperature. The correct answer is d. ideal gas.
Step-by-step explanation:
The question we're addressing is: "This type of gas follows the gas laws at all conditions of temperature and pressure."
An ideal gas is a theoretical concept in chemistry, representing a gas that perfectly follows the kinetic molecular theory. This theory suggests that in an ideal gas, particles do not have any volume and do not exert any attraction or repulsion on one another. However, in reality, these conditions are never fully met as real gases have particles with finite volume and exhibit intermolecular forces. The behavior of a real gas tends to closely resemble that of an ideal gas under conditions of relatively low pressure and high temperature, where the particles are far apart and have sufficient energy to overcome intermolecular forces.
Deviations from ideal behavior are notable under conditions of high pressure and low temperature, where the volume of the particles becomes significant and intermolecular attractions affect the behavior of the gas. Under such conditions, a modified version of the gas laws, which account for these non-ideal interactions, is necessary.
