A heat pump is a device that puts out heat. It involves pumping a lever over and over to get energy so it can work.
<span>Speed is the distance traveled divided by the time it took to travel this distance. Velocity is the change in position divided by the time of travel. Velocity only depends on the starting and ending point but the speed depends on the path. Speed is a scalar quantity (the distance per time ratio) and velocity is a vector quantuty, because it is defined also with its direction.</span>
<u>Answer:</u>
The modern atomic theory has given by "John Dalton and framed postulates".
<u>Explanation:</u>
The fundamental role of atoms in chemistry is established by the modern theory of atoms mentioned in 1808 for the first time by an English scientist named John Dalton. This consists of three sections such as all matter is composed of atoms, atoms of the same element are the same while atoms of different elements are different, atoms combine to form compounds in full-number ratios.
The unique characteristic of the "number of protons" is that all atoms of the same compound share. While the atoms of the same element i.e having a similar number of protons can have different numbers of neutrons and such elements are called isotopes.
Answer:
You would want to build it with bricks because with glass, the sunlight will come through. Also, make sure to have air conditioning.
Explanation:
Three of these are strong electrolytes:
- HCl (Hydrochloric acid)
- HNO3 (Nitric acid)
- NaOH (Sodium hydroxide)
Two of these are Weak electrolytes:
- HF (Hydrogen fluoride)
- HC2H3O2 (Acetic acid)
And the other two are Non-electrolytes:
- C6H12O6 (Glucose)
- C2H5OH (Ethanol)
