Setting concrete at 50°C is preferable to setting it at 5°C. Why? At 50°C, the concrete sets more quickly.
At 50°C, the concrete sets more slowly.
At 50°C, the concrete sets to have a greater final compressive strength.
At 50°C, the concrete sets to have a lesser final compressive strength.

temp rises, and expansion

  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
