It is actually sand, which turns the entire phenomenon hot. Sand cannot hold the heat. It acts like a mirror to the sun. During the daytime, it stays warm, and when the Sun is absent it loses all its heat making the nights colder. There’s nothing in the desert that can either absorb heat from the sun or hold it on the surface when the sun is set.

Because deserts have such little water vapor in the air, it makes it harder to trap heat or cold in a desert. And at night, the sun no longer heats the desert and the heat from the day doesn't stay trapped. Because of this, some deserts can get <em>extremely </em>cold at night, dropping to temperatures below 40F.

In a chemical compound, would you expect an oxide ion to be joined with one atom of calcium or one atom of potassium? Why?

Soloha48 [4]

I know what you're asking but I don't think the question is stated properly. Technically, an atom will not join with an "oxide" ion; i.e., the oxide ion is an atom of oxygen to which two electrons have been added. An oxide ion will add to 2 K ions or 1 Ca ion. The K ion has lost just one electron so it takes two of them to equal the 2- charge on the oxide ion whereas the Ca ion has lost two electrons and it takes only one of them to equal the charge on the oxide ion.

A boy of mass 60 kg and a girl of mass 40 kg are together and at rest on a frozen pond. What is the initial momentum of the boy?

Marianna [84]

The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.

<h3>What is momentum?</h3>

Momentum can be defined as the product of mass and velocity. The S.I unit of momentum is kgm/s.

The initial momentum of the boy can be calculated using the formula below.

Formula:

M' = mu

Where:

M = Initial momentum of the boy

From the question,

Given:

M = mass of the boy = 60 kg
U = Initial velocity of the boy = 0 m/s (at rest)

Substitute these values into equation 1

M = 60(0)
M = 0 kgm/s

Hence, The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.
