The solid metal inner core is the most dense
Answer:
Explanation:
The volume and number of moles are constant, so we can use Gay-Lussac’s Law:
At constant volume and number of particles, the pressure exerted by a gas is directly proportional to its temperature.
Data:
p₁ = 0.500 atm; T₁ = 315 K
p₂ = 0.750 atm; T₂ = ?
Calculations:
Answer is 30.0mL
according to the question dilution is performed by the student which can be calculated with the help of :
EQUATION (1)
Here, we have:
= 3M
= y mL
= 1.80 M
= 50.0mL
putting the known values in equation (1) which will give us value of
3.00× y =1.80 ×50.0
y= 30.0mL
Based on the principle of conservation of energy, the heat capacity of the calorimeter is calculated using the formula:
- c = {m2 × w × (t2 - t1) - m2 × w × (t2 -t1)}/m3 × (t2 -t1)
<h3>What is a calorimeter?</h3>
A calorimeter is an equipment used to determine heat of reaction.
The calorimeter works on the principle of conservation of energy:
Quantity of heat energy is calculated using the formula below:
- q = mass × heat capacity × temperature difference
In the experiment, the following procedure is followed:
- Mass of the hot water, cold water and calorimeter are recorded
- temperature of the hot water is recorded
- temperature of the the cold water and calorimeter is recorded
- final temperature of the mixture is recorded
- heat capacity of the calorimeter is calculated using the formula: heat gained by calorimeter and cold water = heat lost by hot water.
Assuming that;
- mass of hot water = m1
- mass of cold water =m2
- mass of calorimeter = m3
- initial temperature cold water and calorimeter = t1
- final temperature of mixture = t2
- heat capacity of water = w
- heat capacity of calorimeter = c
Therefore, the heat capacity of the calorimeter is calculated using the formula:
- c = {m2 × w × (t2 - t1) - m2 × w × (t2 -t1)}/m3 × (t2 -t1)
