Answer:
The new pressure will be
1000 L, rounded to one significant figure.
Explanation:
Boyle's law states that when a gas is held at a constant temperature and mass in a closed container, the volume and pressure vary inversely. The equation to use is p1v1=p2v2

Answer:</h2>
<h3>What I think is : The protons are present at the centre of the atom with rotating electrons around it so when it is rubbed by fur the electrons get passed from the ebonite rod to the fur leaving the rod negatively charged</h3>

Answer:
A - 8
B - 8
C - O
D - 26
E - 30
F - Fe
Explanation:
Use these things:
1. A = Z + N,
where A - mass number,
Z - atomic number,
N - number of neutrons
2. atomic number = number of protons
Cells are surrounded by #2 , Cell membrane and Cell wall thats what protects the cell
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.
Each element has a specific mass number and a specific atomic number. These two numbers are fixed for an element. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. it has mass number 235 , it means that the sum of neutrons and protons in a carbon atom is 235.3
