Why do you think large differences in temperature between the wet bulb and dry bulb thermometers are possible only at higher tem

Answer:

This is the temperature indicated by a moistened thermometer bulb exposed to the air flow. The evaporation is reduced when the air contains more water vapor. The wet bulb temperature is always lower than the dry bulb temperature but will be identical with 100% relative humidity.

AleksandrR [38]
<h3><u>Full Question:</u></h3>

Oxygen (O_2) and nitrogen (N_2) do not have much greenhouse effect, but several trace gases including carbon dioxide (CO_2), methane (CH_4), nitrous oxide (N_2O), and various chlorofluorocarbons are important greenhouse gases. The primary mechanism by which these greenhouse gases warm the Earth is:

A. Making politicians mad, so they give speeches that heat the air.

B. Experiencing chemical reactions with each other, which release energy.

C. Preventing convection currents that take heat aloft, in the same way that the glass of a greenhouse stops convection currents and so makes the air in the greenhouse warmer.

D. Raising the atmospheric pressure, because squeezing air warms it, as we saw at the Redwoods.

E. Absorbing some of the infrared radiation emitted from the Earth.  

<h3><u>Answer:</u></h3>

The primary mechanism by which these greenhouse gases warm the Earth is absorbing some of the infrared radiation emitted from the Earth.

Option E

<h3><u>Explanation:</u></h3>

Though the pressure does not set the temperature, but the changes in pressure brings changes in temperature. The rare greenhouse gases does not affect the pressure much. The imbalance in greenhouse gases are very less when compared to the effects of radioactive gases. Greenhouse glass blocks the convection currents which is not blocked by greenhouse gases. The infrared radiation emitted from the planet is adsorbed by CO_2.

The CO_2 move into excited state by the infrared photon absorption which quickly returns to the normal state by emission of photon with same energy. These photons emitted from this excitation comes towards Earth which helps in trapping the energy of warming the planet which achieves new balance.

Convert 7.50 grams of glucose C6H12O6 to moles
Lera25 [3.4K]

Answer:

The number of mole is 0.04167mole

Explanation:

To convert gram to mole, we need to calculate the molecular weight of the compound

C6H12O6

C - 12

H - 1

O - 16

Molecular weight = 6 * 12 + 1 *12 + 6 * 16

= 72 + 12 + 96

= 180g/mol

To covert gram to mole

Therefore,

= 7.50g/ 180g/mol

= 0.04167 mole of glucose

. The freezing point of an aqueous solution containing a nonelectrolyte solute is – 2.79 °C. What is the boiling point of this s
Semmy [17]

Answer:

Boiling point of the solution is 100.78°C

Explanation:

This is about colligative properties.

First of all, we need to calculate molality from the freezing point depression.

ΔT = Kf . m . i

As the solute is nonelectrolyte, i = 1

0°C - (-2.79°C) = 1.86 °C/m . m . 1

2.79°C / 1.86 m/°C = 1.5 m

Now, we go to the boiling point elevation

ΔT = Kb . m . i

Final T° - 100°C  =  0.52 °C/m . 1.5m . 1

Final T° =  0.52 °C/m . 1.5m . 1  + 100°C → 100.78°C
