Therefore the pressure if the volume is increased to 4.12L the pressure is

P₂=0.636atm

<h3>What is helium?</h3>

Helium is a chemical element with the atomic number 2 and the letter He. It is a colourless, odourless, tasteless, non-toxic, inert, monatomic gas and the first member of the noble gas group in the periodic chartIt has the lowest melting and boiling points of all the elements.

<h3>What is the purpose of helium and is it a gas?</h3>

Since helium is a safe, non-flammable gas, it is frequently used to inflate balloons for festivities and parades. On the other hand, helium is a crucial component in several sectors, including high-tech manufacturing, medical technology, space exploration, and national security.

The second most prevalent element in the universe, helium, is scarce on Earth. It is the lightest noble gas, colourless, odourless, inert, and has a low boiling point. It is a byproduct of nuclear fusion and radioactive decay.

<h3>Briefing:</h3>

According to Boyle's Law:

P₁ V₁=P₂ V₂

P₁=1.61atm

V₁=2.26L

V₂=4.12L

P₂=(P₁ V₁)/V₂

P₂=((1.61atm)(2.26L))/4.12L

P₂=0.636atm

Boyle's Law states that the volume of a given quantity of gas at a constant temperature is inversely proportional to its pressure, so this makes sense. The pressure must decrease proportionally as the volume rises.

a piece of food is burned in a calorimeter that contains 200.0g of water. If the temperature of the water rose from 65.0°C to 83
Flauer [41]

Answer: 15062.4 Joules

Explanation:

The quantity of heat energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = ?

Mass of food = 200.0g

C = 4.184 j/g°C

Φ = (Final temperature - Initial temperature)

= 83.0°C - 65.0°C = 18°C

Then, Q = MCΦ

Q = 200.0g x 4.184 j/g°C x 18°C

Q = 15062.4 J

Thus, 15062.4 joules of heat energy was contained in the food.
