A Calorie is defined as the amount energy required to raise 1 gram of water by 1 degree Celsius.
79.7cal are required to a phase change in 1 gram of ice to water.
It is being assumed that the temperature of the ice is going to be 0 degrees Celsius, and not any colder. IE, the temperature of the water after its phase change to ice.
So, since we have 60 grams of water, it will take (60*79.7) 4782cal just to complete the phase change of ice to water (cause the water to melt). If the ice measured 0 deg. Celsius, it still measures 0 deg. Celsius at this point.
Now lets raise it by 1 deg. C.
60 Grams of water * 1 cal/degree C rise = 60 calories are required to raise 60 grams of water by 1 deg. C.
4782cal + 60cal = 4842 calories total to cause 60 grams of ice to phase change into water AND cause the water temperature to rise by 1 degree Celsius.
The increase from 3 degrees Celsius to 6 degrees Celsius represents an increase of 3 degrees, not doubling the temperature. Doubling the temperature would require an increase from 3 degrees Celsius to 6 degrees Celsius.
Rainfall does not require the air temperature to be at 0 degrees Celsius. Rain can form at a variety of temperatures depending on the atmospheric conditions present, such as moisture content and temperature gradients.
1 calorie is the energy required to raise 1 gram of water by 1 degree C. So it would take 5 calories to raise it by 5 degrees C.
250 degrees Celsius is equal to 482 degrees Fahrenheit. This temperature is often used in baking for recipes that require high heat to cook quickly or create a crisp outer layer.
Yes it is cold, it's a typical temperature in Winter for most places. Equivalent to approximately 37 degrees Fahrenheit.
To melt 10 grams of ice at 0 degrees Celsius, it would require 80 calories of heat energy per gram, so a total of 800 calories (80 calories/gram * 10 grams = 800 calories) would be needed.
To vaporize 1 gram of boiling water at 100 degrees Celsius, it would require approximately 2260 joules, which is equivalent to about 0.54 calories. This energy is needed to break the intermolecular bonds holding water molecules together, allowing them to escape into the gas phase.
Here's a hint: You need to know the 'specific heat capacity' of ice to be able to answer that question. Try googling for it, or maybe try wikipedia.
The temperature needed to melt rock depends on its composition. On average, rocks require temperatures of 600-1,300 degrees Celsius to melt. However, some types of rock, like granite, may require temperatures well above 1,300 degrees Celsius to melt completely.
Kelvin Or Fahrenheit.Fahrenheit is not a metric unit. Kelvin is the official unit (water freezes at 273.15 K and boils at 373.15 K), but degrees celsius are used colloquially.A kelvin and a degree celsius are the same size, zero kelvin is absolute zero ( the coldest temperature possible) and is -273.15oC.
1 calorie increases 1 gram of water by 1 degree celsius. 4.18 Joules are needed to increase the temperature of 1 gram of water by 1 degree celsius. To reduce the 1 gram of water 1 degree celsius it would have to give off 1 calorie of energy. To calculate the energy multiply the mass in grams of water by 4.18 and by the change in temperature. The energy = 4.18 x m x change in T. The answer is in Joules. If you are using calorie as the unit of energy, replace 4.18 J by 1 C. Note that food is measured in kilocalories (Calories) not metric calories.
Frogs hibernate when the temperature is less than 10 degress Celsius. They can hibernate at temperatures of -7 degrees Celsius at most and can survive in desert temperatures. The highest desert temperature is 49 degrees Celsius, so frogs can probably survive in that temperature. They have a bladder that stores water for them when in HI temperature so they can survive there. They have an ANTIFREEZE chemical element in their body so they can survive in LOW temperatures.
