Question

1.A sample of gas in a closed container occupies 250. mL at 1.25 atm of pressure. If the pressure increases to 2.00 atm while the temperature stays the same, what is the new volume in mL?

2.A sample of gas is held inside a flexible container where pressure is kept constant. At room temperature (21.1ºC), the container has a volume of 1.50 L. What is the volume of the gas if the container is placed in a deep freezer at -10.0ºC?

3.A sample gas is held inside a rigid container with a pressure of 50. kPa and a temperature of 290 K. What is the new temperature of the gas if the pressure is doubled?

Answer 1

Una cantidad de gas ocupa un volumen de 80 cm3

a una presión de 750 mm Hg. ¿Qué volumen

ocupará a una presión de 1,2 atm.si la temperatura no cambia?

Step-by-step explanation:

El volumen inicial de una cierta cantidad de gas es de 200 cm3

a la temperatura de 20ºC. Calcula el

volumen a 90ºC si la presión permanece constante.
