A student heats a liquid on a burner. What happens to the portion of liquid that first begins to warm? Check all that apply.
kherson [118]

Answer:

The answers are options B,D and E

Explanation:

B) The particles in the liquid are slowly overcoming the forces of attraction and spreading out due to the thermal energy they are absorbing. This makes the liquid less dense as it slowly changes into a gas after reaching its boiling point.

D) The particles start absorbing the energy form the surroundings as latent heat of evaporation. They need this energy to overcome the strong forces of attraction between particles to change into the gaseous state

E) The particles have spaced out due to the thermal energy absorbed, making the liquid lighter and it rises upwards.

How is Electric current able to flow?
brilliants [131]
Electric potential on one side of the closed circuit is applied and this causes the electrons to move to a position of lower potential. Imagine this as when you raise an object above the ground and release it. It moves from its higher potential energy position above the ground to its lower potential energy position.

Answer:

3 up 1 across is the answer

Explanation:

Step one: find the Y intercept( Where the line cuts the y-axis)

X = 0

Y = 3(0) (p.s cross out the (o)

y = 2

An ice-making machine inside a refrigerator operates in a Carnot cycle. It takes heat from liquid water at 0.0 degrees Celsius a
avanturin [10]

Answer:

1751399.8902 J

Explanation:

m = Mass of water = 74.6 kg

\Delta H_f = Latent heat of fusion = 3.34\times 10^5\ J/kg

T_h = 19.2°C

T_c = 0°C

We have the equation for cold body

Q_c=m\Delta H_f

We have the equation

\dfrac{Q_c}{Q_h}=\dfrac{T_c}{T_h}\\\Rightarrow Q_h=\dfrac{Q_cT_h}{T_c}\\\Rightarrow Q_h=\dfrac{m\Delta H_fT_h}{T_c}\\\Rightarrow Q_h=\dfrac{74.6\times 3.34\times 10^5\times (19.2+273.15)}{0+273.15}\\\Rightarrow Q_h=26667799.8902\ J

Energy rejected to the room is 26667799.8902 J

Energy supplied to the device is given by

E=Q_h-m\Delta H_f\\\Rightarrow E=26667799.8902-74.6\times 3.34\times 10^5\\\Rightarrow E=1751399.8902\ J

The energy supplied to the device is 1751399.8902 J
