En un restaurante una taza de café está a 100ºC para tenerlo listo para la venta, ya que se enfría al rato a la temperatura del lugar (20ºC), liberando 800 cal al ambiente. Si una persona acude al restaurante para tomarse un buen café para empezar su jornada y le comunican que esta frío y se lo van a calentar a 50ºC, ¿Qué cantidad de calor le proporciona la estufa para lograrlo?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

The material that keeps its new shape after it is stretched is called?

An electron in an x-ray machine is accelerated through a potential difference of 1.00 × 104 v before it hits the target. what is the kinetic energy of the electron in electron volts?
