Solution

The state of matter of ethanol after 60 seconds in a heating water bath would be liquid. This is because the boiling point of ethanol is 78°C. The water bath, even after being switched on for 60 seconds, would not have reached this temperature yet. Therefore, the ethanol would not have vaporized into a gas. Similarly, the temperature of the water bath would be well above ethanol's melting point of -114°C, so the ethanol would not be in a solid state.

Water boils at 100°C while ethanol boils at 78°C.When distilling a mixture of ethanol and water, which liquid would collect in the condenser first? Explain your answer.

The temperature of ethanol in degrees Celsius is read from input into integer variable val. If val is:< -113 degrees Celsius, output "The ethanol is now a solid."≥ -113 degrees Celsius and < 79 degrees Celsius, output "The ethanol is now a liquid."Otherwise, output "The ethanol is now a gas." End each output with a newline.
