Answer:
When put into steam
Explanation:
When a certain amount of steam at boiling temperature condenses (turning into water), the amount of heat released is
where in this case
m = 25.0 g = 0.025 kg is the mass of steam at 100.0°C
is the latent heat of vaporization of water
So,
Instead, the amount of heat released when the water at 100.0°C is cooled down to 34.0°C is given by
where
m = 25.0 g = 0.025 kg is the mass of water
is the specific heat of water
is the change in temperature
Therefore,
Since 
, we can say that your hand will burn more in the first case.
Answer:
120 volts is the root mean square (rms) average of the voltage as it varies with time.
Explanation:
A. The average voltage over many weeks of time (false)
Reason: Average AC voltage over one cycle is cycle (from one peak to other) is zero and so over many weeks of time it is zero.
B. The peak voltage from an AC wall receptacle (false)
Reason: The peak voltage of an AC source in North America is zero.
C. The arithmetic mean of the voltage as it varies with time (false)
Reason: Arithmetic mean AC voltage over one cycle is cycle (from one peak to other) is zero and so over many weeks of time it is zero.
D. One-half the peak voltage (false)
Peak voltage =170 Volts
One-half the peak voltage = 85 volts
E. The root mean square (rms) average of the voltage as it varies with time (True)
Reason:
The peak voltage and root mean square voltage are related by:
Average value of voltage over one cycle is zero, so instead of calculating average voltage for AC peak voltage is first squared and the mean is calculated.
