The one with higher temperature is the one with NaOH as heatis given off during the neutralization reaction that occurs.
<h3>
What is volume?</h3>
Volume can be defined as the amount of space a substance or an objects occupies usually in a closed container.
Volume is measures in litres.
When water is added to dilute acid like HCl, they become more dilute.
When NaOH is added to HCl, a neutralization reaction occurs.
The student will determine the contents of the flasks by adding 10 ml of hcl to each flask. If the NaOH reacts with the Hcl, there will be an increase in temperature.
The increase in temperature is due to the heat of neutralization of the reaction between NaOH and HCl.

Answer:
1.8 L
Explanation:
Given data:
Initial volume of gas = 4.2 L
Initial pressure of gas = 101 kpa
Final volume of gas = ?
Final pressure of gas = 235 kpa
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
101 kpa × 4.2 L = 235 kpa × V₂
V₂ = 424.2 kpa . L/ 235 kpa
V₂ = 1.8 L
So when pressure is increased the volume of gas becomes 1,8 L.

Explanation:
Think about it this way, potential energy is stored energy while kinetic energy is active energy.
<u>Answer</u>:
Lung and Kidneys are associated with this defence.
<u>Explanation</u>:
An aqueous solution that resists change because of the addition of an acid or base solution is known as a buffer. Thus, it comprises of conjugate base and a weak acid. The bicarbonate buffer system is the one that is associated with the respiratory system.
To maintain the pH of and duodenum this buffer system balances carbonic acids, bicarbonate ions and carbon dioxide. It serves to neutralises gastric in the stomach.
