The pressure of a gas depends on the temperature and volume of the gas.
<h3>Ideal gas equation</h3>
PV = nRT
Where
- P is the pressure
- V is the volume
- n is the number of mole
- R is the gas constant
- T is the temperature
From the equation given above, we obtained the following:
PV = nRT
Divide both sides by V
P = nRT / V
R is constant and n = 1
P = T / V
Thus, we can see that the pressure (P) is dependent on the temperature (T) and the volume (V)

Answer:
CnH2n+2 formula
Explanation:
Alkanes have the general formula CnH2n+2, so if an alkane had 7 carbon atoms, it would have the molecular formula C7H16.
C. the square root of 2gh
Explanation:
The square root of 2gh is equivalent to Torricelli's law in the equation.
given expression:
m v² = mgh
to find v, we make it the subject of the expression:
*multiply both sides of the equation by 2:
2 x( m v² )= 2 (mgh)
mv² = 2mgh
*cancel the mass, m appearing on both sides:
v² = 2gh
* find the square root of both side
v = √2gh

- The difference between single displacement reaction and double displacement reaction are:
Explanation:
in the chemical reaction an atom in a molecule is replaced by another atom forming the end product .this type of chemical reaction involved only two reactants for example zinc + copper sulphate give us copper sulphate + copper.double displacement reaction is the reaction in which two compounds react together to form two other compounds by mutual exchange of other ions is called double displacement reaction.this type of reaction is involved two or more than two reactants.for example AG and O3 + NaCl give us agcl + nano3
