it is either "aweak acid or a lousy (or very weak) acid"
Half-life is the time required for the amount of something to fall to half its initial value. This term is usually used in nuclear physics to describe how quickly unstable atoms undergo decay, or how long stable atoms survive, radioactive decay, and it is also used more generally of any type of exponential or non-exponential decay.
In simpler terms: this is when an isotopes radioactivity is cut in half
Answer:
A
Explanation:
I believe the answer is A. An object is every color except the color we see, or the color that bounces off of said object. Therefore if a carpet is yellow, the carpet is every color but yellow. Yellow is the color that it rejects, bounces off of it, and the one we see.
Answer:
The best option is "Heat is transferred by the interaction of moving particles."
Explanation:
The Kinetic Molecular Theory of Heat states that molecules in a fluid increase their speed as temperature increases.
Kinetic theory of heat is a theory that the temperature of a body is determined by the average kinetic energy of its particles and that an inflow of heat increases this energy.
Heat and temperature are related to each other, but are different concepts.
1. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance.
2. Temperature does not depend on the size or type of object.
Also heat can be transferred but temperature can't be transferred.
