Answer:

(A) 800 K (B) 2.4 KW

Explanation:

We have given the COP =1.6

The sink temperature T_L=300K

We have to find the source temperature, that is T_H

(A) We know that COP of the heat pump is given by COP=\frac{T_H}{T_H-T_L}

So 1.6=\frac{T_H}{T_H-300}

1.6T_H-480=T_H

0.6T_H=480

T_H=800K

(B) We have given the work done =1.5 KW

The rate of heat transfer is given by Q_H=COP\times W=1.6\times 1.5=2.4KW

¿Como pasar 254 meses a minutos?<br> Por favor ayudaaa!! <br> Le doy corona a la respuesta
Dimas [21]

Answer:

Ver las respuestas abajo.

Explanation:

Este problema se puede resolver conociendo la relacion entre horas y minutos, sabemos que:

1 hora [h] → 60 minutos [min]

De esta manera:

2 [min] = 2/60 = 0.033 [h]

15 [min] = 15/60 = 0.25 [h]

30 [min] = 30/60 = 0.5 [h]

10 [min] = 10/60 = 0.166 [h]

6 [min] = 6/60 = 0.1 [h]

20 [min] = 20/60 = 0.33 [h]

5 [min] = 5/60 = 0.0833 [h]

Romashka-Z-Leto [24]

Answer:

c) Fullerene and carbon nanotubes because they have empty spaces inside the  molecules

Explanation:

Fullerene and carbon nanotubes would be the most desired in order to hold the cancer fighting drugs and to carry them through the body safely.

  • These molecules have empty spaces in them.
  • The cavities makes it possible for storage.
  • As they pass through the body, they can be held perfectly well to their target site of action.

Potassium metal and chlorine gas combine in a reaction to produce an ionic compound. What is the correct balanced equation for t
Alisiya [41]

Answer:

2K (s) + Cl₂ (g) ⇒ 2KCl (s)

Explanation:

Potassium and chlorine gas combine to form potassium chloride which is an ionic compound. The reaction is a type of combination reaction in which chlorine is being added to the metal, potassium.

Potassium reacts violently with the chlorine which is yellowish green in color to produce white solid of potassium chloride.

The balanced reaction is shown below as:

2K (s) + Cl₂ (g) ⇒ 2KCl (s)
