From high school science class; it takes 144 BTUs to melt a pound of ice. That takes it to 32 degrees F. To then raise the temp to 72 deg., would take about 40 more BTUs.
10 minutes
Attempt to dry it out on a radiator or in the sun for a couple of days (not too hot or it will melt). But sadly, the phone is probably ruined and can't be revived.
Shotgun gauge diameter is determined by how many balls of lead the diameter of that gauge will equal one pound. Thus it takes 10 lead balls of 10 gauge diameter to equal one pound of weight. And 16 lead balls of 16 gauge diameter to equal one pound.Thats why the gauge number decreases when the diameter increases. SHOT SIZE It seems the history of shot size is uncertain. There are at least 24 different methods of determining shot size around the world. The method used in the USA currently is to subtract the shot size number from 17 and that number is the diameter in hundredths of an inch. Thus #4 shot would be 17-4=13 or .13" in diameter. Why 17, I cant find anyone who knows, so anybody know?
Earthing or Grounding is the most prime factor for any electrical/ electronics devices device to avoid any possible risk of electrical shock and proper neutral availability.The number one concern, is prevention of electric shock, which can kill.The secondary concern is prevention of fire. Short circuits draw massive amounts of current which can melt and set fire to the conductors.
0.5 Sq Ft is one half of a square foot. A square foot is an area 1 foot long by one foot wide. A square foot can also be described in inches instead, so the area of one square foot is 12 inches long by 12 inches wide, or 144 square inches. 0.5 Sq Ft is half a square foot, and is equal to 144 square inches multiplied by 0.5, or one half. So half a square foot equals 72 square inches. 1 psi is one pound per square inch. If you spread 1 psi over an area of 72 square inches, you divide the pressure quantity by the area quantity: 1 psi divided by 72 square inches = 1/72 psi, or 0.0139psi.
It takes about 144 BTUs to melt 1 pound of ice at its melting point of 32°F (0°C) and fully convert it into water at the same temperature.
It takes approximately 144 BTUs to change one pound of ice at 20°F to water at 212°F, and an additional 970 BTUs to change the water to steam at 220°F, for a total of 1114 BTUs.
LATENT HEAT OF FUSION When one pound of ice melts, it absorbs 144 BTUs at a constant temperature of 32°F. If one pound of water is to be frozen into ice, 144 BTUs must be removed from the water at a constant temperature of 32°F.

The time it takes for a one pound block of ice to melt depends on the temperature of its surroundings and the rate of heat transfer. In general, it can take anywhere from 45 minutes to a couple of hours for a one pound block of ice to melt at room temperature.
To convert water at 200°F to ice at 30°F, you need to remove 1 BTU to cool water from 200°F to 32°F to become ice. Then, you need to remove 144 BTUs to cool the ice from 32°F to 30°F. So, total BTUs needed to remove from one pound of water at 200°F to end up as ice at 30°F is 144 + 1 = 145 BTUs.
actually its 313.
One pound of steam at 212 degrees Fahrenheit contains 1150 BTUs of energy.
To change one pound of ice at 20°F to steam at 220°F, you need to consider two processes: heating the ice to 32°F, melting the ice at 32°F, heating the water to 212°F, and finally boiling the water to steam at 220°F. The total number of BTUs required for this process is around 1440 BTUs.

The ice cube made of salt and water will melt faster than the one made of sugar and water, which in turn will melt faster than the one made from just water. Salt and sugar lower the freezing point of water, which causes the ice to melt faster.
One pound of natural gas contains approximately 21,500-23,000 BTUs (British Thermal Units). The exact value can vary based on the composition of the natural gas.
