When perfume or cologne is sprayed into the air, it turns into a gas and its particles mix with other air particles that quickly move around the room. This is because gas is the least dense of the three states of matter. It moves quickly into any space or volume because it has the least density. This is called diffusion, when molecules or particles move from areas with high concentration to low concentration areas.

Why is there an energy crisis if energy is supposedly conserved? Explain your answer and cite one example
faltersainse [42]

Answer:

Energy can neither be created nor destroyed, but it does change its form. And not all forms of energy are usable and it gets dissipated as heat energy and sound energy. The energy that is wasted cannot be recovered.

Mixture Problem A jeweler has five rings, each weigh- ing 18 g, made of an alloy of 10% silver and 90% gold. She decides to melt
Tpy6a [65]

Answer:

Explanation:

Total weight of 5 rings

= 18 x 5

= 90 g

silver = 10% of 90 g

= 9 g

gold = 81 g

Let silver added = x gm

Total weight = 90 +x

75% of (90+x) is gold

= 3/4 x  (90+x)g is  gold

So  3/4 x  (90+x)  = 81

(90+x)  = 81 x 4 / 3

= 108

x = 18 g

silver to be added = 18g .
