At the Freezing Point the particles in an object have no kinetic energy
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
Explanation:
The total mass of the product will also be 20g because in chemical reactions, mass is always conserved.
According to the law of conservation of mass "the law states that matter can neither be created nor destroyed but changed from one form to another in a chemical reaction".
- The law simply postulates that mass is conserved in chemical reactions.
- If the mass of reactants is 20g, the mass of the products will likewise be 20g.
- So, the mass is the same in both directions.
