A 5.00 L sample of air at 0 C is warmed to 100.0 C. What is the new volume of the air? First, identify V1.

Answers

Answer 1

Answer:

Answer : The new volume of the air is, 6.83 L

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$(V_1)/(T_1)=(V_2)/(T_2)$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=5.00L\nT_1=0^oC=(0+273)K=273K\nV_2=?\nT_2=100^oC=(100+273)K=373K$

Putting values in above equation, we get:

$(5.00L)/(273K)=(V_2)/(373K)\n\nV_2=6.83L$

Therefore, the new volume of the air is, 6.83 L

We do not run out of water because of the water cycle

Explanation: The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables.

How is Earth like a magnet

Answers

Earth's magnetic field is mostly caused by electric currents in the liquid outer core, which is composed of conductive, molten iron. Loops of currents in the constantly moving, liquid iron create magnetic fields. From afar, the Earth looks like a big magnet with a north and south pole like any other magnet.

Which of the following is not a measure of the quantity of matter?Liters
Degrees Celsius
Grams
Number of molecules

Answers

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Option A, C, D are correct option.

What is matter?

Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.

Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.

So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Degree of Celsius is used to measure temperature which has nothing to do with matter.

Thus option A, C, D are correct option.

I need an answer asap How do scientists determine the number of neutrons in an isotope of an atom?

They subtract the number of protons from the mass number.

They subtract the number of electrons from the mass number.

They subtract the number of protons and neutrons from the mass number.

They add the number of protons and electrons.

Answers

Scientists can calculate the number of neutrons by subtracting the atomic number from the atomic mass.

they subtract the protons

Final answer:

The number of neutrons in an isotope of an atom is calculated by subtracting the number of protons from the mass number.

Explanation:

Scientists determine the number of neutrons in an isotope of an atom by subtracting the number of protons from the mass number of the atom. This is because the mass number of an atom is determined by the sum of its protons and neutrons. Therefore, once you know the total mass number and the number of protons, you can easily calculate the number of neutrons by performing a simple subtraction. For example, if an atom has a mass number of 23 and has 11 protons, it would have 12 neutrons (23-11=12).
