QUESTION 5<br> How can you increase the kinetic energy of the particles in a substance?
FromTheMoon [43]

Answer: A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.

Vanillin (used to flavour vanilla ice cream and other foods) is the substance whose aroma the human nose detects in the smallest
Rudiy27

Answer:

The cost is $0.063.

Explanation:

First, we need to express the volume of the hangar in liters. We know that 1 ft³ = 28.31 L, so using proportions:

5.0 \times 10^{7} ft^{3} .\frac{28.31L}{1ft^{3} } =1.4 \times 10^{9} L

The amount of vanillin required would be:

1.4 \times 10^{9} L.\frac{2.0\times 10^{-11}g }{1L} =0.028g

Finally, the price for such amount of vanillin is:

0.028g.\frac{ \textdollar 112}{50g}=  \textdollar 0.063

Explain what happens to the energy in a wave when a sound is louder.
liraira [26]
Greater amplitude waves have more energy and greater intensity, so they sound louder. ... The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less. This explains why even loud sounds fade away as you move farther from the source.
