The kinetic energy of a charged particle is related to the electric field potential via the following equation:

1/2*m*v² = q* E -----(1)

where m = mass of the particle

v = velocity

q = charge

E = potential

since kinetic energy KE = 1/2mv², eq (1) can be written as:

KE = q*E

i.e kinetic energy of a charge is directly proportional to the strength of the electric field potential (E)

Therefore, as the charge moves from a higher to a lower potential, its kinetic energy will also decrease.

Ans: B)

The kinetic energy decreases

If a gas has a volume of 1000 ML at a temperature of 23°C and a pressure of 100 mmhg, what is it’s volume under standard conditi
Colt1911 [192]

Answer:

119.7 mL.

Explanation:

  • From the general law of ideal gases:

<em>PV = nRT.</em>

where, P is the pressure of the gas.

V is the volume of the container.

n is the no. of moles of the gas.

R is the general gas constant.

T is the temperature of the gas (K).

  • For the same no. of moles of the gas at two different (P, V, and T):

<em>P₁V₁/T₁ = P₂V₂/T₂.</em>

  • P₁ = 100.0 mmHg, V₁ = 1000.0 mL, T₁ = 23°C + 273 = 296 K.
  • P₂ = 1.0 atm = 760.0 mmHg (standard P), V₂ = ??? mL, T₂ = 0.0°C + 273 = 273.0 K (standard T).

<em>∴ V₂ = (P₁V₁T₂)/(T₁P₂) </em>= (100.0 mmHg)(1000.0 mL)(273.0 K)/(296 K)(760.0 mmHg) =  121.4 <em>mL.</em>

What is the effect of thermal energy on the atoms/molecules in a sample of matter?​
Anestetic [448]

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
