Think about the lab procedure you just read. label each factor below with v for variable or c for constant. temperature of the gas: volume of the gas in the syringe: weight put on the syringe: number of moles of gas in the syringe: mass of gas in the syringe: number of gas molecules in the syringe: hypothesis: if the pressure on a gas is increased, then its volume will decrease because the gas molecules will be pushed closer together. (this is in accordance with boyle's law): p = kv-1 the words underlined above are the only variables for the lab procedure; the other factors are constant. therefore, this procedure will you test the hypothesis.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

hope i !

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
