Ostrovityanka [42]
False, Dietary proteins are first broken down to individual amino acids by various enzymes and hydrochloric acid present in the gastro-intestinal tract.

A steel bottle contains argon gas at STP. What is the final pressure if the temperature is changed to 115°C?
Lorico [155]

Answer:

Final pressure is 1.42atm

Explanation:

Based on Gay-Lussac's law, pressure of a gas is directely proportional to its absolute temperature. The equation of this law is:

P₁T₂ = P₂T₁

<em>Where P is pressure and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>

In the problem, initial conditions are Standard Temperature and Pressure, STP, that are 1 atm and 273.15K.

If the final temperature is 115°C = 388.15K (115°C + 273.15 = 388.15K), using Gay-Lussac's law:

P₁T₂ = P₂T₁

1atmₓ388.15K = P₂ₓ273.15K

1.42atm = P₂

<h3>Final pressure is 1.42atm</h3>
