Help pls 7. There is a gas with 1 atm of pressure in 9L volume at 20 degrees Celsius. Calculate
the
final temperature at 5 atm pressure with 4L.
8. a gas occupies a gas occupies a volume of 2 L at 20°C and 1,05 atm. Calculate the volume
end at 60 degrees Celsius and 2.4 atmospheres of pressure.
9. A sample of 0.5 L of nitrogen is collected at 2 atm and 20ºC. If the temperature is
rises to 30°C and the volume decreases to 0.1L, what pressure will the nitrogen have?

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.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
