Answer:
Step-by-step explanation: If a large cloud encounters a colder air mass, it tends to rise up in the sky. On the other hand, the cold air mass sinks toward the surface. This happens because temperature is a property that affects the density of substances. Colder substances are denser than warm substances.
Here we want to study what might happen when a cloud encounters a colder air mass.
Here we got the situation where a cloud (which is already a cold mass) encounters a colder air mass at a temperature of 5°C (this don't really matter, as we do not know the exact temperature of the cloud).
As you might know, there is something called dilation. This phenomenon causes that as we increase the temperature of something, it usually increases its volume.
And we know that density is mass over volume, so if we increase the temperature, we decrease the density.
Then we will see that (not always) colder masses are less dense than hotter ones.
Particularly, if a cold air mass finds a hot air mass, the cold air mass will move below the hot one, because it has more mass in less volume.
Something similar happens with clouds (not exactly, because the cloud has a different composition than air, so even when the cloud is colder than the air, the cloud could have a larger or equal density, but let's assume that this is not the case).
Then what we should expect to see when the cloud meets the colder air mass, is that the cloud increases its height and the air mass decreases its height. In the process, wind currents may be made (this is actually really complex, so it can or not happen, and it happens the direction and magnitude of these can be really hard to predict) that may impulse the cloud in some given direction.
