1) Un móvil viaja a 40 km/h y comienza a reducir su velocidad a partir del instante t=0. Al cabo de 6 segundos se detiene completamente.

radiation warms things up temp rises convection currents air circ windy weather

  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

conservation of mass

mass before something happens = mass afterwards
