3. Three metal spoons are on a table. They are each at room temperature. If the three spoonstouch,
heat will flow among all three spoons.
heat will flow between two spoons.
no heat will flow among the spoons.
o heat will flow from the spoons to the air.

Answers

Answer 1

Answer: If the spoons touch, no heat will flow among the spoons. This is because they are already at thermal equilibrium with each other. This is hinted by the statement "they are at room temperature" which means they all have the same temperature. Heat only flows when there is a difference in temperature.

This experiment is to see if water flows faster out of a smaller can or a larger can. You will need: • two cans (one quite small like a soup can and the other large, like a juice, can.)Follow these steps: A. Remove the top of each can. Punch a hole in the side of each can, very close to the bottom, making sure the holes are equal in size. Cover each hole with a piece of tape, and place the cans next to the sink.B. Put water in both cans, making sure the water is at the same level - different amounts, but the same level. Turn the cans so the holes are facing into the sink, and remove the tape at the same time. Answer these questions: Do the streams of water shoot out at the same distance? Why or why not?C. Try the same experiment, but this time put one cup of water in each can. What happens to the streams of water now?D. Try the same experiment, but this time fill both cans to the top. What happens to the streams of water?ANSWER A B C AND D CORRECTLY!!!

Which type of energy increases when an object’s atoms move faster? A.nuclear B.mechanical C.chemical D.thermal

Answers

Answer: The correct option is D.

Explanation:

Thermal energy is the internal energy of the object due to the motion of the particles.

The kinetic energy is due to the motion of the particles. If the system has kinetic energy then it will have thermal energy.

When the object's atoms move faster then the thermal energy increases.

Therefore, the correct answer is thermal energy.

When an object's atoms move faster, its thermal energy increases and the object becomes warmer.

As the mass and volume increases, the densit will
Increase, decrease, or remain the same

Answers

We can't tell from the information given.

Density is the RATIO of mass to volume. So, if mass and volume both
increase but their ratio decreases, then the density decreases.

But if mass and volume both increase and their ratio also increases,
then the density increases.

Examples:

-- Start with a pile of some kind of substance.
Mass = 150 grams
Volume = 100 cm³

Density = (mass) / (volume) = (150 gm)/(100cm³) = 1.5 gm/cm³

-- Add 50 grams of mass. Mass = 200 gm.
Add 50 cm³ of volume. Volume = 150cm³.

   Density = (mass) / (volume) = (200 gm)/(150 cm³) = 1.33 gm/cm³.
Density decreased.

-- To the original pile, add 100 grams of mass. Mass = 250 gm.
   add 50 cm³ of volume. Volume= 150 cm³.

   Density = (mass) / (volume) = (250 gm)/(150 cm³) = 1.67 gm/cm³.
Density increased.

-- To the original pile, add 60 grams of mass. Mass = 210 gm.
   add 40 cm³ of volume. Volume = 140 cm³.

   Density = (mass) / (volume) = (210 gm)/(140 cm³) = 1.5 gm/cm³.
     Density no change.
   Same as the original pile.

Do change that cannot be easily reversed such as burning observe the law of conservation of mass
