Why is the Northern Hemisphere warmer when tilted to the sun?

Chemistry
1 answer:
AnnZ [28]2 years ago
3 0

Answer:

The Sun gives off UV radiation and heat waves, when tilted closer, it is closer to that UV radiation and heat waves.

For example, if you put a heat lamp closer to a rock the rock would get warmer, if you put it further away it would receive less heat therefore making less warmer.

David is making lemonade he asked you could you some lemon juice and water the sugar starts to dissolve what can we do to speed
suter [353]

We could (a) stir faster and (b) warm the mixture.

<em>Stirring faster</em> moves freshly-dissolved sugar away from the solid and allows new water molecules to contact with the surface,

<em>Warming the mixture</em> gives the water molecules more kinetic energy, so their collisions with the surface of the sugar will be more effective in removing the sugar molecules.

Atmospheric pressure at the summit of mount everest is about one third the pressure at sea level, which is 760 mm hg. if oxygen
vichka [17]
Atmospheric pressure at sea level is 760 mmHg.
We have been told that at the summit the pressure is only one third the pressure at sea level.
Then the pressure at the mountain top is \frac{760}{3} mmHg
Air is made of a mixture of gases. the pressure that each gas exerts individually contributes to the total pressure of the system. The pressure that each gas exerts is the partial pressure of that gas which depends on the mole fraction of that gas or percentage composition of the individual gas.
Partial pressure of Oxygen - total pressure x percentage composition
Therefore pO₂ - \frac{760 * 0.21}{3} = 53.2 mmHg
Answer is 53 mmHg

When elemental iron corrodes it combines with oxygen in the air to ultimately form red brown iron(iii) oxide which we call rust.
iren [92.7K]
<span>The mass of the nail would increase, because the iron is adding oxygen to its chemical composition. This would increase the overall mass. If the mass increases from 23.2g to 24.1g, then the increase would be the difference between the two masses, or 0.9g.</span>
