Compound X is a colorless liquid at room temperature. A sample of pure X was slowly heated from -5℃, which is below its melting point, to 90℃, which is above its boiling point. Its temperature is measured every minute and the results are represented on the graph.What is the significance of t°C?A 1

Compound X is a colorless liquid at room temperature. A sample of pure X was slowly heated from -5℃, which is below its melting point, to 90℃, which is above its boiling point. Its temperature is measured every minute and the results are represented on the graph.

Dalton’s completing an investigation in the science lab. He observes that a sample of liquid turns to gas at 135°C. What’s this temperature called? A. boiling point B. freezing point C. melting point D. room temperature E. standard temperature

The boiling point of a compound is the temperature at which a liquid is converted to the phase.

The temperature on a sample of pure X held at 0.70atm and −52.°C is increased until the sample boils. The temperature is then held constant and the pressure is decreased by 0.16atm. On the phase diagram below draw a path that shows this set of changes.

In an experiment, the temperature of a liquid at 16.9 degrees Celsius is decreasing at a rate of 2.3 degrees Celsius per minute and the temperature of a solid at 30.7 degrees Celsius is decreasing at a rate of 6.9 degrees Celsius per minute. Enter the number of minutes it will take the liquid and solid to reach the same temperature.
