Which process lets convection plays a role in the water cycle?

Sergio039 [100]

The best and most correct answer among the choices provided by your question is the third choice or letter C.

Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection plays a role in the water cycle when " gases cycle up and down based on air pressure."

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

The specific heat of lead is 0.0380 cal/g·°C. If 47.0 calories of energy raised the temperature of a lead sample from 28.3°C to

ollegr [7]

Answer:

Mass of lead, m = 687 g

Explanation:

The expression for the calculation of the enthalpy change of a process is shown below as:-

$\Delta H=m\times C\times \Delta T$

Where,

$\Delta H$ is the enthalpy change

m is the mass

C is the specific heat capacity

$\Delta T$ is the temperature change

Thus, given that:-

Mass = ?

Specific heat = 0.0380 cal/g°C

$\Delta T=30.1-28.3\ ^0C=1.8\ ^0C$

Heat added = 47.0 calories

So,

$47.0=m\times 0.0380\times 1.8$

Mass of lead, m = 687 g

Tell whether the following pairs of compounds are identical, constitutional isomers, stereoisomers, or unrelated. (a) cis-1,3-Di

Aleks04 [339]

Answer:

(a) Constitutional Isomers

(b) Constitutional Isomers

Explanation:

Constitutional isomers are also known with the name Structural Isomers. These are the compounds which have same chemical formula but differ in arrangement of atoms i.e. structure.

Both the compounds cis-1,3-dibromocyclohexane and trans-1,4-dibromocyclohexane have the same chemical formula $C_{6} H_{10} Br_{2}$ but have different structure as shown in the image below.

In the second case the compounds 2,3-dimethylhexane and 2,3,3-trimethylpentane, both have same chemical formula $C_{8} H_{18}$ but have different structures which is shown in the image below.

Thus it is clear that in both the groups (a) and (b) the given compounds are Constitutional Isomers.
