<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

<h2>_____________________________________</h2><h2>CALORIMETER:</h2>
Calorimeter is device used for the measurement of heat. In a calorimeter we can use the temperature change of water to quantify an amount of heat. A calorimeter just captures all the energy released (or absorbed) by a reaction in the water. So Option A and B are wrong as calorimeter don't have anything to do with providing the heat or letting the the heat in, as it is the insulated calorimeter too.
<h2>_____________________________________</h2><h2>Energy in the reaction:</h2>
In the formation of any bond there is equal amount of heat required as to break that bond. It means Energy released in the making of bond is equal to the energy required in the breaking of the bond. So Option D is wrong as it says we need more energy in making then breaking.
<h2>_____________________________________</h2><h2>Enthalpy:</h2>
Enthalpy is the total heat content of the system. As we provide energy to the reactants and the product is formed, so The enthalpy(heat content) of product is more than the Enthalpy of the reactant, Thus Option C is correct.
Enthalpy is denoted by H or Q, its formula is,
H = U + PV
Where,
U is internal energy
PV is equals to Work done ; P = Pressure, V = Volume

Answer:
You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up. Or by multiplying all the sides of the container. #markasbrainliest
Answer:
2p
Explanation:
To solve this question, we can use Boyle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:

where
p is the pressure of the gas
V is its volume
The equation can be rewritten as

where in this problem we have:
is the initial pressure of the Xe(g) gas
is the initial volume of the Xe(g) gas
is the final volume of the Xe(g) gas
Solving for p2, we find the final pressure of the gas:

So, the final pressure is twice the initial pressure.
Answer:

Explanation:
Since the temperature is held constant, we only need to focus on the volume and pressure. We will use Boyle's Law, which states the volume of a gas is inversely proportional to the pressure. The formula is:

Originally, the gas had a volume of 150 milliliters and a pressure of 3.0 atmospheres. We can substitute these values into the left side of the equation.

The original gas was compressed to a volume of 50 milliliters, but we don't know the volume.

Now, we need to solve for the new pressure (P₂). Multiply on the left side first.

Since we are solving for the pressure, we need to isolate the variable. It is being multiplied by 50 mL. The inverse of multiplication is division. Divide both sides by 50 mL.


The units of milliliters will cancel.


The new pressure is <u>9 atmospheres.</u>
