Calculate the total energy transferred when 200 g of ice cubes at 0°C are changed to steam at 100°C.
uranmaximum [27]

Answer:

604000\ \text{J}

Explanation:

m = Mass of ice = 200 g

\Delta T = Temperature change of water = (100-0)^{\circ}\text{C}

c = Specific heat capacity of water = 4200 J/kg °C

L_f = Specific latent heat of fusion = 340 kJ/kg

L_v = Specific latent heat of vaporisation = 2260 kJ/kg

Heat required to convert ice to water = mL_f

Heat required to raise the temperature of water to boiling point = mc\Delta T

Heat required to convert water to steam = mL_v

Total heat required

q=mL_f+mc\Delta T+mL_v\\\Rightarrow q=m(L_f+c\Delta T+L_v)\\\Rightarrow q=0.2(340\times 10^3+4200(100-0)+2260\times 10^3)\\\Rightarrow q=604000\ \text{J}

Heat required to convert the given amount of ice to steam at the required temperature is 604000\ \text{J}.

Listening to the radio, you can hear two stations at once. Describe this wave interaction
Sedaia [141]
Actually says Pantazis, since their frequencies are so wildly different, brain waves don’t interfere with radio waves. Even if that was the case, brain waves are so weak, they are hardly measurable at all. For comparison, says Pantazis, “the magnetic field of the earth is just strong enough to move the needle of a compass. Signals from the brain are a billionth of that strength.”
