Answer:
Temperature
Explanation:
It's called temperature.
This is because, in any substance an increase in temperature means that the particles on the average will move with greater speeds, or that they have greater kinetic energy while a decrease in temperature means that the particles on the average will move with lesser speeds, or that they have lesser kinetic energy.
The final temperature inside the container is 77.5°C
<h3>Solution ; </h3>
There are two heat transfers involved:
heat lost by bolt 1 + heat gained by bolt 2 = 0
-q(heat released by iron bolt) at higher temperature = q(heat gained by iron bolt) at lower temperature
-(cm)(T2-Treat higher temperature) = (cm)(T2-Tre at lower temperature)
-[0.450/(J/g-K) × m × (T2 -100°C)] = [0.450/(J/g-K) × m × (T2 -55°C)]
Or, -(T2 - 100°C) (T2 - 55°C) T2+T2 = 100°C + 55°C
Or, T2 = 155°C /2 = 77.5°C
<h3>What is Specific Heat ?</h3>
Specific heat is the amount of heat necessary to increase the temperature of one gram of a substance by one degree Celsius. Specific heat is often measured in calories or joules per gram per Celsius degree. Water, for example, has a specific heat of one calorie (or 4.186 joules) per gram per Celsius degree.

Answer:
Acid + Base -------> Salt + Water
Explanation:
The reaction between an acid and bases is called a neutralization reaction. The result of the reaction is salt and water. For example, when hydrochloric acid(acid) and sodium hydroxide(base) react they form sodium chloride(salt) and water. Also, heat is evolved.
Example:
HCl + NaOH ----------> NaCl + H2O
HCl is hydrochloric acid.
NaOH is sodium hydroxide which is a base.
NaCl is sodium chloride which is a salt.
H2O is water.
