Answer from: Quest
the unit of the measure =
explanation:
the property that is quantified by the energy needed per of material to raise the temperature by one.
si unit of energy = joule (j)
si unit of temperature = kelvin (k)
si unit of mass of material = kilogram (kg)
the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.
the unit of specific heat is
Answer from: Quest
the right answer is 0.3 meters per second
Answer from: Quest
An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move.
