The pressure of a gas is the force that a gas exerts per unit area of the container.
Pressure is defined as force per unit area. Gas molecules are constantly colliding against the walls of the container. The pressure of the gas is the force the gas is exerting on its container.
Since temperature is defined as the average kinetic energy of the molecules of a gas then the higher the temperature, the faster the particles move.
The volume of a container refers the size if the container.
The pressure of a gas is inversely proportional to its volume according to Boyle's law. Thus implies that if the pressure of the gas goes up, the volume has to go down.
For a compound to be called an acid, it must contain H+ and H3O+ when dissolved in water.
For a compound to be called a base, the compound must dissolve in water to yield hydroxide ions.

The answer is heat.
To use a glue gun, it has to use heat to heat up so that it can melt the glue.
Answer:
158 L.
Explanation:
What is given?
Pressure (P) = 1 atm.
Temperature (T) = 112 °C + 273 = 385 K.
Mass of methane CH4 (g) = 80.0 g.
Molar mass of methane CH4 = 16 g/mol.
R constant = 0.0821 L*atm/mol*K.
What do we need? Volume (V).
Step-by-step solution:
To solve this problem, we have to use ideal gas law: the ideal gas law is a single equation which relates the pressure, volume, temperature, and number of moles of an ideal gas. The formula is:
Where P is pressure, V is volume, n is the number of moles, R is the constant and T is temperature.
So, let's find the number of moles that are in 80.0 g of methane using its molar mass. This conversion is:
So, in this case, n=5.
Now, let's solve for 'V' and replace the given values in the ideal gas law equation:
The volume would be 158 L.
Note that it says oxygen "gas"
So you need the atomic mass of oxygen gas
Look at your periodic table, you'll see 15.9994 under oxygen
Oxygen gas has a formula of O2 therefore,
(15.9994) times 2= Oxygen gas atomic mass=31.9988
Mol= Mass/Atomic Mass
=62.3 g/ 31.9988 g/mol = 1.95 mol
now look at the ratio of C2H6 and O2, notice there is an invisible number beside each of them, at that "invisible number" is =1
1 C2H6 + 1 O2 -> products
this means that for 1 mol of C2H6, 1 mol of O2 has to react with it
Thus as we have 1.95 moles of O2, we need 1.95 moles of C2H6
Explanation:
Most Americans have encountered some bacteria at some point in their lives, whether it was acquired from restaurant food or a grocery store, which caused them to claim they later had food poisoning. There are multiple nasty bacteria that can cause this, and there are many misconceptions about how they end up in our food, and what the best ways to avoid them are. To be forewarned is to be forearmed, so here are several misconceptions about food safety and the practices involved that can leave us satisfied, or ruin our day with stomach churning nastiness.
