a 5 g ice cube starts life at -1 C if 2182.5 j are added to it what will be the final temperature upon his demise ?

Answers

Answer 1

Answer:

Final Temp = 23.92°C

Explanation:

ΔH(total) = (m·c·ΔT)ice + (m·ΔH(f))melt'g + (m·c·ΔT)water

2182.5j = (5g)(2.092j/g·°C)(1°C) + (5g)(334.56j/g) + (5g)(4.184j/g·°C)(ΔT)

(2182.5 - 10.46 - 1672.8)j = 20.92j/°C·ΔT

ΔT = (2182.5 - 10.46 - 1672.8)j / 20.92j/°C = 23.92°C

Since the melting ice starts and ends at 0°C and is then warmed to 23.92°C then the temperature change is also the final temp of the water based upon given energy input values.

Which statement describes particles of an ideal gas, based on the kinetic molecular theory?

Answers

Answer:

There are 5 steps/rules of the ideal gases based on kinetic theory.

Explanation:

1. Particles in a gas are constant moving in random motion.

2. combined volume of the particles is negligible.

3. particles exert no forces on one another

4. any collisions between the particles are completely elastic

5. the average kinetic energy of particles is proportional to temperature in kelvins.
