How is heat transferred through space
Heat is transferred by energy waves moving through space. Explanation: According to research: Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible
Please give brainiest if possible, I kinda need it. Thnx!
Answer:
the transfer of energy through space is called radiation. through radiation there is no direct contact between heat source and object. sunlight radiation warms the earth's surface; radiation can also come from fires.
A gas has an initial volume of 15L and the pressure is at 2atm. If the temperature increases from 330K to 462K and the pressure reduced to 1 ATM, what is the new volume of the gas?
Answer:
42L
Explanation:
Using the combined gas law equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the provided information in this question, P1 = 2atm, V1 = 15L, T1 = 330K, T2 = 462K, P2 = 1atm, V2 = ?
Using the formula;
P1V1/T1 = P2V2/T2
2 × 15/330 = 1 × V2/462
30/330 = V2/462
Cross multiply;
462 × 30 = 330 × V2
13860 = 330V2
V2 = 13860 ÷ 330
V2 = 42L
The new volume is 42L

How many atoms are in 4.5 g of AICI3?
Answer:
2.047 × 10^22 atoms.
Explanation:
To calculate the number of atoms (nA) in AlCl3, we first need to find the number of moles in the compound, AlCl3.
Molar mass of AlCl3 = 27 + 35.5(3)
= 27 + 106.5
= 133.5g/mol
Using mole = mass/molar mass
mole = 4.5/133.5
mole = 0.034moles
number of atoms in a substance (nA) = number of moles (n) × Avagadros number or constant (6.02 × 10^23 atoms)
nA of AlCl3 = 0.034 × 6.02 × 10^23
nA = 0.2047 × 10^23
nA = 2.047 × 10^22 atoms.

A. 0.64 m
B. 1.6 m
C. 0.064 m
D. 16 m
The wavelength of the wave in brass medium, given that the wave has a frequency of 300 Hz is 16 m (Option D)
How do I determine the wavelength in brass?The wavelength of a wave is defined according to the following formula:
Velocity (v) = wavelength (λ) × frequency (f)
Divide both sides by frequency
Wavelength (λ = Velocity (v) / frequency (f)
With the above formula, we can obtain the wavelength of the wave in the brass medium. Details below:
Frequency (f) = 300 HzWave speed in brass (v) of = 4700 m/sWavelength in brass (λ) = ?Wavelength (λ = Velocity (v) / frequency (f)
Wavelength in brass = 4700 m/s / 300 Hz
Wavelength in brass= 16 m
Thus, we can conclude that the wavelength is 16 m (Option D)

Answer:
b
Explanation:
This means that it takes more energy or heat to increase water's temperature than it does for most other substances. The specific heat of water is greater than that of dry soil, therefore water both absorbs and releases heat more slowly than land.

Which energy resource produces the least amount of air pollution?
coal
natural gas
oil
hydropower
Answer:
hydropowered
Explanation:
took the test
Hydropower is the energy source that produces the least amount of air pollution. Therefore, the correct option is option D.
What is energy?Energy is The capacity or ability to do tasks, such as the ability to forcefully move an object. Energy can exist in a multitude of forms and can change from one to another, including thermal, mechanical, chemical, and nuclear energy. The flow of electric charges known as electrons is what generates electrical energy.
Energy is utilised to make a wide range of goods, power transportation, and power the appliances we use to heat and light our houses. The production of electricity is the main purpose of these various energy sources. All of these many energy sources contribute to the electrical power reserve that is then distributed to various locations via high-powered lines. Hydropower is the energy source that produces the least amount of air pollution.
Therefore, the correct option is option D.

Two layers of earth have convection currents
Answer: Mantle and core are the two layers of the earth that have convection currents.
Explanation:
The mantle and outer core are the two layers that are associated with the convection currents. In the mantle the convection currents occur due to the heat emerging out of the core also mantle region releases heat. If the transfer of heat or convection currents stop then the mantle will not flow and the core will not produce magnetic field at all. This will lead to coldness in earth and earth will lose the protection from harmful radiations.

When is the Northern Hemisphere tilted toward the Sun?
Answer: Summer Solstice
In North America, around June 21, Earth tilts on its axis toward the Sun. This is called the summer solstice, and it is when the Northern Hemisphere has the most daylight of any time of the year. It is also when the Sun appears to be the highest in the sky, and it has its greatest angle to Earth.
The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator.
