3. A certain gas is used in a constant-volume gas thermometer to measure the melting point of a certain solid. Measurements of the pressure in the thermometer are made at the temperature of the melting point (when the pressure is found to be 1.8 atm) and at the temperature of the triple point of water (when the pressure is found to be 0.4 atm). What is the melting temperature in degrees Celsius? What was the amount of gas in the thermometer if its volume V-10 cm? Assume 1 atm = 105 Pa. Choose the correct options. (You may assume that the gas in the thermometer behaves as an ideal gas.) A 195 C E 10 mol B 956 C F 1.76x10* mol C 283 C G 1.1x10 mol D 479 C H 2.3x10 mol
