The actual formula for volume for a cube is the length multiplied by the width and then multiplied by the height. Since all three measurements are the same, the formula results in the measurement of one side cubed. For the example, 5^3 is 125 cm^3. Multiply the volume by the known density, which is the mass per volume.

Answer:
296.43 K is the temperature of a vessel when pressure reads 1.250 atm.
Explanation:
At STP, when pressure is 1.000 atm the value of temperature is 273,15 K.
If the pressure at temperature T reads as 1.250 atm.
Applying Gay Lussac's law:
(At constant volume)
296.43 K is the temperature of a vessel when pressure reads 1.250 atm.
the correct answer is A.
Each atom has three sub particles, which are electron, proton and neutron. To get the atomic mass for each atom, one has to add the masses of the proton, neutron and electron in an atom. For each atom, the major contributors to its mass are proton and neutron, this is because the mass of the electron is very small indeed. Thus, the atomic mass of an element is usually in the range of its mass number, which is obtained by the summation of proton and neutron. Since it is the number of proton that indicate an atomic number and it is the mass number that indicate atomic mass, therefore, atomic mass can be greater than the atomic number.
Answer:
B. particles in an object move faster
Explanation:
At higher temperatures, particles in an object moves faster.
Temperature is the degree of hotness or coldness of a body.
- At higher temperature, the substance is very hot.
- Temperature is related to the heat energy content of a body
- As the temperature increases, the average kinetic energy of the particles of system increases more and more.
- This is in compliance with the kinetic molecular theory of matter.
- Therefore, at higher temperatures, particles in an object move faster.
