Answer:
The amount of energy transferred to the diamond while being cut is thus Q = 852000 J
Explanation:
Since quantity of heat transferred Q = mcΔθ where m = mass of substance , c = specific heat capacity of substance and Δθ = temperature change.
Now, given that for diamond, m = mass of diamond = 600 g, c = specific heat capacity of diamond = 710 J/g°C and Δθ = temperature change = 2 °C.
So, the amount of energy transferred to the diamond while being cut is thus
Q = mcΔθ
Q = 600 g × 710 J/g°C × 2 °C
Q = 852000 J
So, the amount of energy transferred to the diamond while being cut is thus Q = 852000 J
Answer:
<h3>The answer is 3754.33 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 21.7 kg = 21700 g
volume = 5.78 cm³
We have
We have the final answer as
<h3>3754.33 g/cm³</h3>
Hope this helps you
Answer:
0.20 moles
Explanation:
In order to solve this problem it is necessary to keep in mind the definition of molarity:
- Molarity = moles / liters
If we<u> input the data given by the problem</u> we're left with:
Meaning that we can proceed to <u>calculate the number of moles</u>:
The idea here is that one mole of any ideal gas that is kept under standard temperature and pressure, STP, conditions will occupy 22.4 L
