What are electrical signals in the brain? The average human brain contains about 120 billion neurons, which constantly receive and send information through branch-like appendages called dendrites. Chemical or electrical signals that reach the dendrites produce small voltage changes across the cell’s membrane, which are routed to the cell body. Do humans have electrical activity […]

What is the main difference between physical and chemical properties?
What is the main difference between physical and chemical properties? A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a […]
How is hydrogen bonding responsible for high surface tension?
How is hydrogen bonding responsible for high surface tension? When many water molecules form hydrogen bonds with other water molecules, they form a lattice of water molecules, which is strong and flexible. This creates a high surface tension. As a result, this molecule at the surface tends to be pulled into the bulk of the […]
