How are the temperatures of tropical seawater and polar seawater different?

Chemistry
1 answer:
sveticcg [70]3 years ago
8 0

Explanation:

o At the polar latitudes the surface temperature remains near the freezing point of sea water about -1.9°C. Pure water freezes at 0°C and boils at 100°C under normal pressure conditions. When salt is added the freezing point is lowered and the boiling point is raised

o The water temperature of tropical oceans thus typically exceeds 20°C and stays relatively constant troughout the year. Particularly intense radiation directly over the equator evaporates seawater and forms a mass of very warm, humid tropical air that subsequently rises and cools as it flows north and south

What is the average kinetic energy of 1 mole of a gas that is at 100 degrees Celsius?
Paha777 [63]
The average kinetic energy of an ideal gas is calculated as 

KE_avg = 3/2 kT

where T is the temperature in Kelvin and k=R/N_A; R is the universal gas constant and N_A is the number of moles.

Thus, upon substitution we get

KE_avg = 3/2(8.314/1)(100+273)
KE_avg = 3/2(8.314)(373)
KE_avg = 4651.683

The average kinetic energy of 1 mole of a gas at 100 degree Celsius is 4651.683 J.

nata0808 [166]
<span>Uranium-236 is intermediate nuclei. created by fusion reactions an unstable isotope of uranium created from four hydrogen atoms used in the H-bomb.

Following is the reaction involved in above process:

</span>^{235}U+ ^{1}n →  ^{236}U→ ^{144}Ba + ^{89}Kr + 3 ^{1}n<span> + 177 MeV
</span>
Here, 
^{235}U = Fission material,
^{1}n = projectile,
^{236}U = intermediate nuclei,
^{144}Ba and ^{89}Kr = Fission product

What is the kinetic energy of a 5 kg object moving at 7 m/s?
valina [46]

Answer:

122.5 Joule, or 122.5 j

Explanation:

Given,

mass of the object (m) = 5 kg

velocity of the object (v) = 7 m/s

Kinetic energy = \frac{1}{2} × m × v²

Applying the formula:

Kinetic energy = \frac{1}{2} × 5 × 7²

⇒ \frac{1}{2} × 5 × 7 × 7

⇒ \frac{245}{2}

⇒ 122.5 Joule, or 122.5 j

Kinetic energy is the energy that an object gains as the result of the motion.  It also depends on the mass of the object and force with which the motion is applied.  In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.
