Due to "<u>Temperature</u>" difference heat is transferred from "one object" to "another object".

<u>Explanation</u>:

In general there are three ways for heat to be transferred: Conduction (heat is transferred by vibration of particles), Convection (heat is transferred by movement of particles) & Radiation (heat is transferred in Infrared waves). Heat is also called as thermal energy which acts as kinetic energy when energy is given to atoms, molecules, ions in solids, liquids and gases due to which movement takes place. As heat flows from higher temperature to lower temperature and heat content “Q” of an object depend upon its specific heat “c” and its mass “m”. For example when ice cube is added to room temperature water then transfer of heat energy will take place due to which ice melts in water and both of them reach to a common temperature which is also called as “Thermal Equilibrium” phase.

Greenhouse gases act to <u>increase</u> temperatures by <u>absorbing</u> thermal infrared radiation.

We have already learned that Earth's atmosphere is composed often of nitrogen and oxygen. Those gases are transparent to incoming solar radiation. they may be also transparent to outgoing infrared radiation, which means that they do not take in or emit sun or infrared radiation.

The multiplied quantities of greenhouse gases human sports are adding to the environment have dissatisfied the balance that has been in location for the reason that ceases of the closing ice age, including greater greenhouse gases decreases the amount of infrared radiation energy leaving the atmosphere.

Greenhouse gases inside the ecosystem time and again absorb and re-radiate infrared radiation (warmth). strength radiated from Earth's surface as warmth, or infrared radiation is absorbed and re-radiated by using greenhouse gases, impeding the loss of warmth from our surroundings to area.

Which formula is an empirical formula?

poizon [28]

<h2>Hello!</h2>

The answer is:

The empirical formula is the option B. $NH_{3}$

The empirical formula of a compound is the simplest formula that can be written. On the opposite, the molecular formula involves a variant of the same compound, but it can be also simplified to an empirical formula.

$MolecularFormula=n(EmpiricalFormula)$

We are looking for a formula that cannot be simplified by dividing the number of molecules/atoms that conforms the compound.

Let's discard option by option in order to find which formula is an empirical formula (cannot be simplified)

A. $N_{2}O_{4}$

It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.

$N_{2}O_{4}=2(NO_{2})$

B. $NH_{3}$

It's an empirical formula since it cannot be obtained by the multiplication of a whole number and the simplest formula. It's the simplest formula that we can find of the compound.

C. $C_{3}H_{6}$
