In which sample is the average kinetic energy of the particles the greatest?
tangare [24]
Temperature is a measurement of average kinetic energy of the particles in a sample which means that the sample with the highest temperature has the highest average kinetic energy of the particles.

That being said the answer would be 4) 10 mL of H2O (l) at 35 degrees Celsius since that sample has the largest temperature.

I hope this helps.  Let me know if anything is unclear.

What is the specific heat of the solid phase? (Please see picture attached)
ValentinkaMS [17]

Answer:

B.0.2 J/g°C

Explanation:

From the attached picture;

  • Heat attained in the solid phase is 200 Joules
  • Change in temperature is 50°C ( from 0°C to 50°C)
  • Mass of the solid is 20 g

We are required to determine the specific heat capacity of the substance;

  • We need to know that Quantity of heat is given by the product of mass,specific heat capacity and change in temperature.
  • That is; Q = mcΔT

Rearranging the formula;

c = Q ÷ mΔT

Therefore;

Specific heat = 200 J ÷ (20 g × 50°c)

                      = 0.2 J/g°C

Thus, the specific heat of the solid is 0.2 J/g°C
