Answer: B) Electromagnetic waves can travel through empty space.

Explanation:

Conduction: This type of heat transfer happens when there is direct contact between the two object.  Example: heating a pan on stove.

Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents. Example: Heating of swimming pool.

Radiation: This type of heat transfer happens when there is direct transfer of energy through empty space.The electromagnetic radiation from the surface of an object which is due to the object's temperature is radiation. Example: Heating of earth's surface.

why does nitrogens lewis structure have 5 dots around it while nitrogens Bohr diagram has seven dots around it?
leonid [27]

Answer:

Bohr diagram shows electrons orbiting the nucleus. Nitrogen has 7 electrons orbiting the nucleus

Lewis structure is the simplified Bohr diagram. It only shows the electrons in the outer shell. For Nitrogen, 2 electrons are in the first shell. The remaining 5 electrons are in the outer shell.

How many moles of sucrose<br> are in 5.25x1029 sucrose<br> molecules?
Pavel [41]

Answer:

872093.02moles

Explanation:

Given parameters:

Number of atoms of Sucrose  = 5.25 x 10²⁹atoms

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.

             6.02 x 10²³ atoms makes up 1 mole of an atom

             5.25 x 10²⁹ atoms will contain = \frac{5.25 x 10^{29} }{6.02 x 10^{23} }  = 872093.02moles

How much heat is absorbed by 20g granite boulder as energy from the sun causes its temperature to change from 10°C to 29°C? The
Nataly [62]

Given :

Mass of granite , m = 20 g .

Change in temperature , \Delta T=29-10=19^oC.

Specific heat capacity of granite , C=0.79\ J/g^oC .

To Find :

The heat absorbed by granite .

Solution :

We know , heat absorb is given by :

\Delta H=mC\Delta T\\\\\Delta H=20\times 0.79 \times 19 \ J\\\\\Delta H=300.2\ J

Therefore , heat absorb is 300.2 J .

Hence , this is the required solution .
