WebA constant-volume gas thermometer is used to measure an unknown temperature. At the temperature of boiling water, the absolute pressure of the gas in the bulb is 1.227 × 1 0 5 Pa. The absolute pressure is 1.145 × 1 0 5 Pa at the unknown temperature. What is that temperature on the Celsius scale to the nearest degree? temperature: WebIn the previous example, the water was at room temperature, and it slowly evaporated. If the water was warmer, it would have evaporated faster. In contrast, boiling occurs only when the liquid reaches a certain temperature, which we call the boiling point.
