Explanation:

As it is given that melting point of copper is 1084^{o}C. So, it means liquid state of copper will exist at a temperature greater than 1084^{o}C.

Whereas, it is known that liquid state of water exists at above zero degree celsius.

And, kinetic energy of the particles of a substance is directly related to the temperature as follows.

                    K.E = \frac{3}{2} kT

Hence, more is the temperature of a substance more will be the kinetic energy of its molecules.

Therefore, temperature of liquid copper is more than the temperature of liquid water.

Thus, we can conclude that the energy of the particles in a certain amount of liquid copper is greater than the energy of the molecules in the same amount of liquid water.

VA 19.75-g sample was heated by 12.35 calories. The specific heat of the sample is 0.125 cal/g°C. What was the initial temperatu
SOVA2 [1]

Answer:

31.9 °C  

Explanation:

The formula for the heat q absorbed by an object is

q = mCΔT where ΔT = (T₂ - T₁)

Data:

q = 12.35 cal

m = 19.75 g

C = 0.125 cal°C⁻¹g⁻¹

T₂ = 37.0 °C

Calculations

(a) Calculate ΔT

q = mCΔT

12.35 cal = 19.25 g × 0.125 cal°C⁻¹g⁻¹ × ΔT

12.35 = 2.406ΔT °C⁻¹  

ΔT  = 12.35/(2.406 °C⁻¹) = 5.13 °C

(b) Calculate T₂

ΔT = T₂ - T₁

T₁ = T₂ - ΔT = 37.0 °C - 5.13 °C = 31.9 °C

The original temperature was 31.9 °C.

S<br> SIO₂ +3C Sic +20o<br> Sic ? mass in grams<br> С c-
seraphim [82]

Answer:

26.74g

Explanation:

The equation of the reaction is;

SIO₂ + 3C --> SiC +2CO

From the balanced equation, the relationship between SiC and C is;

3 mol of C produces 1 mol of SiC

Converting mol to mass using; Mass = moles * Molar mass

Mass of SiC = 1 mol * 40.11 g/mol = 40.11g

This means;

3 mol of C produces 40.11g of SiC

2 mol of C produces xg of SiC

3 = 40.11

2 = x

x = 2 * 40.11 / 3 = 26.74g
