Regents Chemistry June 2026 11 Gas behavior becomes more ideal when a gas has a (1) higher temperature and a lower pressure (2) higher temperature and a higher pressure (3) lower temperature and a lower pressure (4) lower temperature and a higher pressure Solution: Real gas becomes more like an ideal gas at high temperature and low pressure. Choice 1 is the correct answer. LINKS: Regents Chemistry Guides and Solutions Chemistry Tutoring More Regents Chemistry Practice

Regents Chemistry June 2026 10 Which sample of argon gas has atoms with the highest average kinetic energy? (1) 40 g of argon gas at 20°C (2) 30 g of argon gas at 40°C (3) 20 g of argon gas at 60°C (4) 10 g of argon gas at 80°C Solution: Temperature is the measure of the average kinetic energy. The higher the temperature, the higher the kinetic energy. We are looking for the answer choice with the highest temperature. Choice 4 is the correct answer. LINKS: Regents Chemistry G
