Law of action-reaction

Answers

Answer 1
Answer:

Answer:

Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

What is the difference between conduction and convection?

Answers

These are both ways heat travel. Conduction is when something is touching something i.e. When you touch a hot pan. Convection is heat rising, then cooling so it sinks and heats back up and rises again repetitively i.e. A convection oven (think circulation of heat)
CONVECTION is the transfer of heat from high temperature to low temperature with movement of mass or medium due to temperature difference in the region. Although, convection is a bit similar to conduction, but convection involves movement of substances. Such as wind system in our planet. Air moves due to temperature difference in every part of our planet. Then, CONDUCTION is the transfer of heat, of course from high temperature to low temperature when two objects (such as metals) are in direct contact (without the movement of metals).

3.00 moles of helium gas (He) are in a container with a volume is 2.00 liters and a temperature is at 298 K. What is the approximate pressure in kilopascals?

Answers

Answer:

3718.628 kPa.

Explanation:

  • We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm (P = ??? atm).

V is the volume of the gas in L (V = 2.0 L).

n is the no. of moles of the gas in mol (n = 3.0 mol).

is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of the gas in K (T = 298.0 K).

∴ P = nRT/V = (3.0 mol)(0.0821 L.atm/mol.K)(298.0 K)/(2.0 L) = 36.7 atm.

  • To convert from atm to kPa:

∵ 1.0 atm = 101.325 kPa.

∴ P = (36.7 atm)(101.325 kPa/1.0 atm) = 3718.628 kPa.
