On a chilly, humid evening, intermolecular forces enable fog to form. The gaseous water molecules condense as a result of powerful molecular interactions.

What force allows fog formation?

From the south, warm, moist air is brought in, and if there is snow or cool precipitation on the ground, it will come into touch with the warm, moist breezes. The air coming in will cool as a result of this air-ground contact. Dew point rises at that position, leading to high humidity and the formation of fog.

What is molecular interactions?

Interactions between molecules or between atoms without bonds are referred to as molecular interactions. There are three types of molecular interactions: cohesive (attraction between like), adhesive (attraction between unlike), and repulsive forces.

A 12.5 g sample of granite initially at 82.0 oc is immersed into 25.0 g of water that is initially at 22.0 oc. what is the final
Paraphin [41]

The amount of heat lost by granite is equal to the amount of heat gained by water. Therefore their change in enthalpies must be equal. The opposite in sign means that one is gaining while the other is losing

ΔH granite = - ΔH water

ΔH is the change in enthalpy experienced by a closed object as it undergoes change in energy. This is expressed mathematically as,

ΔH = m Cp (T2 – T1)

Given this information, we can say that:

12.5 g * 0.790 J / g ˚C * (T2 – 82 ˚C) = - 25.0 g * 4.18 J / g ˚C * (T2 – 22 ˚C)

9.875 (T2 – 82) = 104.5 (22 – T2)

9.875 T2 – 809.75 = 2299 – 104.5 T2

114.375 T2 = 3108.75

T2 = 27.18 ˚C

The temperature of 2 objects after reaching thermal equilibrium is 27.18 ˚<span>C.</span>

If Earth is in the portion of its orbital path that is further from the Sun, then what can be determined about its rate
Maurinko [17]
If the earth's orbit is far from the sun, then, its rate will be slower than when it is closer to the Sun. When gravitational field lines get closer together, the magnetic force is strong. We know that the heavier the body is, the stronger its gravitational pull.<span>

If the dimensions of a cube-shaped cell with a volume of 1 pm were to
melamori03 [73]

Answer:

B

Explanation:

Assuming the units are all supposed to be the same

A cube shaped cell with a 1 um³ volume would have a dimensions of 1 x 1 x 1   (because volume = length x width x height and 1 x 1 x 1 =1)

If we double the dimensions, we have a cube with the dimensions 2 x 2 x 2.

The surface area of each face of the cube is the length x width, so 2 x 2. This means the surface area of each face of the cube is 4 um².

There are 6 faces of a cube, so the total surface area is 6 x 4 um² = 24 um².
