Answer:
When the substance is cooled, its temperature will fall below 78 °C after 100% of the vapor has changed to liquid.
Explanation:
- Boiling point is the temperature at which a liquid changes state from liquid form to gaseous form without change in temperature. It may defined as the temperature at which the vapor pressure is equal to the pressure of the gas above the liquid.
- A liquid with a boiling point of 78°C, it means that, when the liquid is heated, its temperature will start rising above 78 °C after 100% of the liquid has changed to vapors. Additionally, when the liquid is cooled, its temperature will fall below 78 °C after 100% of the vapor has changed to liquid.

Explanation:
Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases.
Answer:
mass = 100kg
Explanation:
Hello! In order to calculate the mass, we first have to calculate the volume of the tube.
For this, we have the area (A) and the length (L) of the tube.
V = A * L
A = 100cm2 * (1m2 / 10000cm2) = 0.02m2
L = 5m
V = 0.02m2 * 5m = 0.1m2
Then we can calculate the area from the density.
Density = mass / volume
mass = density * volume = 1000 (kg / m3) * 0.1m3
mass = 100kg
