A container holds 2.0 of liquid water. The water absorbs 477 kJ of energy. If the water's initial temperature was 298 K, what is it's final temperature?

Explanation:

Here mass of water not given directly but volume of water is given and we already know the density of water so we will use the volume density relationship to find mass.

volume=2L

density=1kg/L

mass=2kg=2000gram

initial temperature=298K=25C

specific heat of water (C)=4.186 joule/gram

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
