When does ice storm happen?
Ice storms happens when a cold mass of air and a warm mass of air combine to create a ice storm
If 100 g of ice at 0 C is added to 300 g of water at 60 C Assuming no transfer of heat to the surroundings what is the temperature of the liquid water after all the ice has melted?
The final temperature of the liquid water after all the ice has melted will be 20 degrees Celsius. This can be calculated using the principle of conservation of energy, where the heat lost by the water in cooling down from 60°C to the final temperature is equal to the heat gained by the ice in melting and then heating up to 20°C.
Does it take more thermal energy to raise the temp of 6 grams of water by 8 degrees C or 5 grams of ice by twenty degrees C?
It takes more thermal energy to raise the temperature of 5 grams of ice by 20 degrees Celsius. This is because you need to first melt the ice, which requires additional energy (the latent heat of fusion) before you can raise the temperature of the resulting water.
If Jocko has a mass of 60 kg and stands at rest on ice catches a 20 kg ball that is thrown to him at 10 kmh How fast does Jocko and the ball move across the ice?
According to the law of conservation of momentum, the total momentum before the catch should equal the total momentum after the catch. Since the initial momentum of the ball is 200 kgm/s, the final momentum after the catch will also be 200 kgm/s shared between Jocko and the ball. The final velocity can be calculated using momentum = mass * velocity. Jocko and the ball will move across the ice at the same final velocity.
What is the potential energy of a 20 kg safe on a shelf 0.5 meters above the ground?
The potential energy of the safe can be calculated using the formula: Potential energy = mass x gravitational acceleration x height. Plugging in the values, we get: Potential energy = 20 kg x 9.8 m/s^2 x 0.5 m = 98 Joules. Therefore, the potential energy of the safe is 98 Joules.
What is the number of grams of ice that can be melted by 1 g of 100c steam?
There is no mass loss (nor gain) in state change, so there would be 100 grams of ice formed.
Years ago, a 20 kg block of ice was used daily in the home icebox to keep food cool The temperature of the ice was zero degrees Celsius when delivered How much heat did the ice absorb by the time it?
The heat absorbed by the ice can be calculated using the formula Q = m * L, where Q is the heat absorbed, m is the mass of the ice (20 kg), and L is the latent heat of fusion for ice (334 kJ/kg). Therefore, the ice absorbed 20 kg * 334 kJ/kg = 6680 kJ of heat as it melted.
What are facts about the Antarctic ice sheets?
1. Ice sheets contain enormous quantities of frozen water. If the Greenland Ice Sheet melted, scientists estimate that sea level would rise about 6 meters (20 feet). If the Antarctic Ice Sheet melted, sea level would rise by about 60 meters (200 feet). 2. The Antarctic and Greenland ice sheets contain more than 99 percent of the freshwater ice on Earth. 3. An ice sheet is a mass of glacial land ice extending more than 50,000 square kilometers (20,000 square miles).

How do you know if ice cubes reach room temperature?
You can tell if ice cubes have reached room temperature by observing if they have completely melted. Once they have melted, the water will reach room temperature. Placing a thermometer in the water can also confirm if it has reached room temperature.
Years ago, a 20 kg block of ice was used daily in the home icebox to keep food cool. The temperature of the ice was zero degrees Celsius when delivered. How much heat did the ice absorb by the time it all melted?
6,660,000 J
Ice has a density of 92gcm3 What is the mass in kg of 20m3 if ice?
Ice has a density of 916,8 kilograms per cubic meter or 0.9128 grams per cubic centimeter. 20 cubic meters of ice weigh then 20 times 916,8 = 18336 kilograms = 18.336 tonnes.
When ice melts why doesn't the temperature rise?
When ice melts, the absorbed heat energy is used to break the intermolecular bonds holding the solid structure of ice together, rather than increasing the temperature of the ice. This is known as the latent heat of fusion, and it occurs at a constant temperature until all the ice has melted.
What thermal power is required to change 2.5kg of ice into water at 20 degrees celsius in 2 minutes?
The thermal power required can be calculated using the formula: Power = (mass * specific heat capacity * change in temperature) / time. Given data: mass = 2.5kg, specific heat capacity of ice = 2100 J/kg°C, specific heat capacity of water = 4200 J/kg°C, change in temperature = 20°C, and time = 2 minutes. First calculate the energy required to melt the ice (from -10°C to 0°C), then to heat the water to 20°C. Finally, divide the total energy by the time in seconds to get the thermal power.
What is the kinetic energy of an object that has a mass of 20 kilograms and a speed of 2.8ms?

What is the kinetic energy of an object with a mass of 30kg and a velocity of 20 ms?
6,000 J
