No, that's only partially correct
Atmospheric pressure on Earth at its surface is 101 KPa (101 kilopascals or 101,000 N/m2). Which of these statements is true?
If we pump out the gas in a closed container leaving only 1 billionth of the original gas there will still be more than 1010 (10 billion) atoms per cm3 in the container.
If we pump out the gas in a closed container leaving only 1 billionth of the original gas there will be fewer than 100 atoms per m3 in the container.
When we reduce the pressure in the container while keeping the temperature constant, the number of atoms per m3 must stay constant.
At 1 atmosphere, the number of atoms/m3 in air at room temperature is about 109, one billion atoms.

In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen, with 1.00 mol of methane as a by-product. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting. A single astronaut exhales 1,08 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts' respiration during one week of flight is stored in an originally empty 165-L tank at -45.0°C, what is the final pressure in the tank?

The trip took about 22 days, and the fish consumed energy at a rate of 2.0 W for each kilogram of body mass. About 80% of this energy is released by burning fat and the other 20% by burning protein. How many grams of fat are burned? One gram of fat releases 3.8×10^4J of energy. If the salmon is about 15% fat at the beginning of the trip, how many grams of fat does it have at the end of the trip?arrow_forward

- Imagine that you have air in a sealed glass container that has a volume of 1 liter. The pressure inside the container is 1013 hPa and the temperature is 20◦C. You now inject cloud droplets into the chamber without letting any air leak out. The droplets have a radius of 10 micrometers, and you inject a concentration of drops that is typical of what you find in a cloud (200 drops per cm3). Will there be a change in the gas pressure? If so, by what amount? Please provide a calculation. What does your answer tell you about the presence of particles in the atmosphere and their potential influence on pressure?arrow_forwardThe average temperature of the atmosphere has increased by 0.4°C over the last thirty years. Estimate how much energy has gone into warming up the planet in this way. Keep in mind that the atmosphere has a mass of 5 × 1018kg, and the specific heat capacity of air is about 1 Jg−1K−1.

Although temperatures very close to 0 K have been produced in laboratories, absolute zero has never been attained. In fact, evidence suggests that absolute zero cannot be attained. How did scientists determine that 0 K is the “lower limit” of the temperature of matter? What is absolute zero on the Celsius scale?arrow_forwardSelect all the correctly defined terms. (Hint: do not select the ones that are incorrectly defined) Law of conservation of energy presumes the total energy content of the universe is constant. Kinetic energy is attributed to the motion of the obicet and depends on the mass of the object and its velocity. O Potential cnergy is the energy associated with position or composition. Heat involves the transfer of energy between two objects due to a temperature difference. Work is a force acting over a distance Could also be transfer of cnergy from onc form to anotherarrow_forward
