The temperature of 6.24 l of a gas is increased from 25.0°c to 55.0°c at constant pressure. the new volume of the gas is question 18 options: 2.84 l. 6.87 l. 13.7 l. 5.67 l.

Heating this gas to 55 °C will raise its volume to 6.87 liters.

Assumption: this gas is ideal.

Explanation:

By Charles's Law, under constant pressure the volume of an ideal gas is proportional to its absolute temperature (the one in degrees Kelvins.)

Alternatively, consider the ideal gas law:

.

Therefore the volume of the gas is proportional to its absolute temperature.

Either way,

.

.

For the gas in this question:

Convert the two temperatures to degrees Kelvins:

Apply Charles's Law:

.

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.
