chapter 10 review physical characteristics of gases Mathematical expression: \( \frac{P_1}{T_1} = \frac{P_2}{T_2} \) Implication: Increasing temperature raises pressure if volume remains fixed. 4. Avogadro’s Law Statement: At constant temperature and pressure, volume and moles of gas are directly proportional. M R Ramon Torphy Dec 3, 2025
ch14 concept review heat and temperature answers required to raise the temperature of 200 g of water from 20°C to 100°C? Given: m = 200 g c = 4.18 J/(g·°C) (specific heat of water) ΔT = 100°C - 20°C = 80°C Solution: Q = mcΔT = 200 g × 4.18 J/(g·°C) × 80°C = 200 × 4.18 × 80 = 67,072 J Answer: Approximately 67,072 joules of heat are needed.
