Answer:
If the temperature and volume ot a gas increases, the r.m.s. velocity of the molecules in the gas will be 2 times the original r.m.s. molecular velocity.
If T doubles while V is held constant, the new net internal energy of the gas will be 2 times the original internal energy of the gas.
Explanation:
Temperature and root mean square velocity are directly proportional to one anoth. If the temperature increases, root mean square velocity also increases and vice versa, while temperature is also directly proportional to the internal energy of the gas molecules, higher the temperature, higher will be the internal energy and lower the temperature so internal energy will be decreased.
Answer:
This is considered a hypothesis because it hasn't been confirmed. It is just a guess.
Explanation:
A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. Law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. However, Newton's law doesn't explain what gravity is, or how it works.
Answer:
solids
Explanation:
through solids because the molecules are closer together
The mass of copper (Cu) is 63.55 grams.
Remember that 6.022×10²³ atoms = 1 mol (Avogadro's number).
To get from grams to atoms, you need to multiply 1.2 grams of copper × 1 mol of copper × 6.022×10²³ atoms of copper and divide it by 63.54 grams of copper and 1 mol of copper.
This will cancel out the grams and moles to give you the answer in atoms of copper!
1.2 grams of copper × 1 mol of copper × 6.022×10²³ atoms of copper
63.54 grams of copper x 1 mol of copper
= 1.137×10²² atoms of copper
= round to 2 sig figs: 1.1×10²² atoms of copper
