Option Z is correct. The stainless steel container was likely the hottest. Stainless steel is an excellent heat conductor because it quickly warms the substance.

<h3 /><h3>What are the qualities of stainless steel?</h3>

Stainless steel is an excellent heat conductor because it quickly warms the substance or allows heat to travel through it. Stainless steel is also corrosion-resistant.

Foam, glass, and plastic, on the other hand, are all poor heat and electrical conductors. As a result, they do not allow heat to travel through.

As a result, we may deduce that, among the available possibilities, the stainless steel container was most likely the hottest.

Hence Option Z is correct. The stainless steel container was likely the hottest.

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

Can a twig float on water?
Irina18 [472]
Yes a twig will float on water

1 g/cm³- density of water

roughly 0.50–0.75 g cm-3-density of twig

because a twig is less dense than water the twig will float
