How does a convection current circulate a fluid?

Chemistry
1 answer:
poizon [28]3 years ago
3 0

Answer:

Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid.

A tablespoon of very hot water is added to a pint of very cold water. What will happen to the temperature of the water?
prohojiy [21]
Well although the amount of hot water is slight, and there's much more cold water, I would assume that the water would more than likely increase in temperature.... even though it may be slight

If ∆G◦ = 27.1 kJ at 25◦C for the reaction CH3COOH (aq) + H2O (l) → CH3COO− (aq) + H3O+ (aq), calculate Ka for this reaction at 2
frosja888 [35]

Answer:

Ka = 1.78 × 10⁻⁵

Explanation:

Let's consider the following thermochemical equation.

CH₃COOH(aq) + H₂O(l) → CH₃COO⁻(aq) + H₃O⁺(aq)   ∆G° = 27.1 kJ/mol

At 25°C (298 K), we can find the equilibrium constant (Ka) using the following expression.

∆G° = - R × T × lnKa

where,

R: ideal gas constant

T: absolute temperature

27.1 × 10³ J/mol = - (8.314 J/K.mol) × 298 K × lnKa

Ka = 1.78 × 10⁻⁵

Where did the fahrenheit temperature scale get its name?
____ [38]

Answer:

Daniel Gabriel Fahrenheit

Explanation:

he 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30° and 90° for the freezing point of water and normal body temperature, respectively; these later were revised to 32° and 96°, but the final scale required an adjustment to 98.6° for the latter value.
