The specific heat of water is 4.184 J/ g°C, the specific heat of wood is 1.760 J/g°C, and the specific heat of coal is 1.26 J/g°
Tomtit [17]

Answer:

D. Water

Explanation:

Specific heat is defined as the amount of heat you need to add to a substance per unit of mass to increase its temperature in 1°C.

That means if you have the same mass of substances, the one with the higherst specific heat is the one that requires the most amount of heat to increase its temperature by one degree Celsius.

As you can see, water is the material with the highest specific heat doing the material that requires the most heat.

Right answer:

<h3>D. Water </h3>

A presión de 3atm, 7L de un gas a temperatura constante experimenta un cambio ocupando un volumen de 0,5L ¿Cuál será la presión
pantera1 [17]

Answer:

La presión que ejerce es 42 atm.

Explanation:

La ley de Boyle relaciona la presión y el volumen y dice que  el volumen ocupado por una determinada masa gaseosa a temperatura constante, es inversamente proporcional a la presión.

La ley de Boyle se expresa matemáticamente como:

P*V=k

Ahora es posible suponer que tienes un cierto volumen de gas V1 que se encuentra a una presión P1 al comienzo del experimento. Si varias el volumen de gas hasta un nuevo valor V2, entonces la presión cambiará a P2, y se cumplirá:

P1*V1= P2*V2

En este caso:

  • P1= 3 atm
  • V1= 7 L
  • P2= ?
  • V2= 0.5 L

Reemplazando:

3 atm* 7 L= P2* 0.5 L

Resolviendo:

P2=\frac{3 atm*7 L}{0.5 L}

P2= 42 atm

<u><em>La presión que ejerce es 42 atm.</em></u>
