Kernels of corn are heated and become popcorn. Why is this a chemical change?

Answers

Answer:

When popcorn is popped, liquid inside the kernel is changed to steam. Pressure from the steam builds up inside the kernel. When the pressure reached a critical stage the kernel pops turning itself inside out. This is a physical change.

20 PTS!!! Jack said that unprocessed oil is a mixture of many organic compounds. Jane said that unprocessed oil needs to be processed so that individual compound can be isolated. Who made the correct statement and why?

1. Jack is correct, unprocessed oil is a mixture of many organic compounds. Jane is not correct, they do not need to be processed to be used.
2. Jack is incorrect, unprocessed oil is not a mixture of many organic compounds. Jane is correct, unprocessed oil needs to be processed to be used.
3. Both Jack and Jane are correct. Unprocessed oil, petroleum, is a mixture of organic compounds that need to be isolated or separated to be used.
4. Neither Jack nor Jane are correct. Unprocessed oil, petroleum, is not a mixture of organic compounds and it does not need to be isolated or separated to be used.

Temperature and kinetic energy have a relationship.

Answers

Answer:

[tex]\boxed {\boxed {\sf Temperature=Average \ kinetic \ energy}}[/tex]

Explanation:

Temperature is also known as the average kinetic energy in a substance.

If there is an absence of heat in a substance, the particles move slower and the kinetic energy decreases. The temperature will be lower, because there is less kinetic energy.

If heat is present or applied, the particles move more, so kinetic energy increases. The temperature will be higher, since there is more kinetic energy.

So, the relationship is: temperature is the measure of average kinetic energy.

What is the amount of heat energy absorbed when 36 grams of ice at -20oC is melted to water at 0oC?

Answers

Answer:

Q = 1461.6 J

Explanation:

Given data:

Mass of ice = 36 g

Initial temperature = -20°C

Final temperature = 0°C

Amount of heat absorbed = ?

Solution:

specific heat capacity of ice is 2.03 j/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

ΔT =  0°C - (-20°C)

ΔT = 20°C

Q = 36 g ×2.03 j/g.°C×20°C

Q = 1461.6 J
