By Gayle-Lussac's law, the pressure and temperature of a fixed volume and amount of gas is directly proportional.
Thus,
P/T = constant
So if the temperature is increased four times, the pressure is also increased four times.
Answer:
The answer is a
Explanation:
conduction is the transfer of thermal energy when two substances of different temperature touch.
Answer:
Pure substances cannot be separated into any other kinds of matter, while a mixture is a combination of two or more pure substances. ... A pure substance has constant physical and chemical properties, while mixtures have varying physical and chemical properties.
Explanation:
Chemical reactions are in equilibrium when there is no net change in the reactants or products.
Chemical equilibrium refers to the situation in a chemical reaction where both the reactants and products are present in concentrations that have no further tendency to change over time, preventing any discernible change in the system's properties. When the forward reaction and the reverse reaction go forward at the same speed, this condition results. The forward and backward reactions typically have equal, if not zero, reaction rates. As a result, the concentrations of the reactants and products do not fluctuate much, indicating that the chemical reaction is in equilibrium.

Answer:
The ratio of atoms of potassium to atoms of oxygen is 2:1
Explanation:
As the equation given is :
<h3>
</h3>
The product formed is 2 moles of potassium oxide .
Amount of potassium atom in the potassium oxide is 2 atoms of potassium and amount of oxygen atom present here is 1 atom of oxygen .
But we have 2 moles of potassium oxide . So, the potassium and oxygen atoms will be multiplied by 2 .
Hence , we get 4 atoms of potassium and 2 atoms of oxygen .
Ratio of potassium to oxygen atoms is - 4:2
Therefore , 2:1
