Is it true that a quantity of ice at zero degrees Celsius must contain less total energy than the same quantity of water at zero degrees Celsius?
Yes indeed. The energy required to change (ice) to (water at the same temperature) is known as the latent heat of fusion. It's an intrinsic property of each substance, and is quite large for water, which is one of the reasons why ice is a preferred substance to use for cooling drinks ... one ice cube removes a lot of heat from the drink in its process of melting.

What does -270 degrees Celsius mean?
(-270) degrees Celsius = (-454) degrees Fahrenheit
Which sample of water contains the most heat energy 10 g at 10 degreescelsius or 20 g at 10 degrees celsius?
The sample of water that contains the most heat energy is the 20 g sample at 10 degrees Celsius because it has double the mass of the 10 g sample. Heat energy is directly proportional to mass, so the sample with more mass will contain more heat energy.
What amount of energy is released when you freeze then cool a 75g of liquid water to -20 degrees Celsius?
To freeze liquid water at 0 degrees Celsius, you need to remove 334 J/g of energy. To cool it from 0 degrees Celsius to -20 degrees Celsius, you need to remove an additional 80 J/g. Therefore, for 75g of water, the total energy released would be 75g * (334 J/g + 80 J/g) = 33,200 J.
How many calories are needed to convert 12.5 grams of ice at 0 degrees Celsius to steam at 100 degrees Celsius?
To convert 12.5 grams of ice at 0 degrees Celsius to steam at 100 degrees Celsius, you would need to provide heat energy for three main processes: heating the ice from 0 degrees Celsius to 100 degrees Celsius, melting the ice into water at 0 degrees Celsius, and then heating the water from 0 degrees Celsius to steam at 100 degrees Celsius. The total calorie requirement would be determined by the specific heat capacities and heat of fusion and vaporization of water.
How does the vapor pressure of water at 10 degrees celsius compare with its vapor pressure at 50 degrees celsius?
The vapor pressure of water at 10 degrees Celsius is lower than at 50 degrees Celsius. As temperature increases, so does the vapor pressure of water because more water molecules have enough energy to escape into the gas phase.
What is temperature different from?
At day we have 20 degrees Celsius (68 degrees Fahrenheit) and at night we have 10 degrees Celsius (50 degrees Fahrenheit). The temperature difference between day and night is 10 degrees Celsius or 18 degrees Fahrenheit.
Is heat energy measured in units of joules degrees Celsius and in degrees Fahrenheit?
Heat energy is typically measured in joules (J) or calories (cal). Degrees Celsius and degrees Fahrenheit are units of temperature, not energy.
Explain whether your body gains or loses thermal energy if your body temperature is 37 degrees Celsius and the temperature around you is 25 degrees Celsius?
25degres celsius has more thermal energy
Heat is measured in Celsius degrees true or false?
False. Heat is measured in units of energy such as calories or joules, not in degrees Celsius. Temperature, on the other hand, is measured in degrees Celsius.
How much energy is required to transform solid water at 0 degrees Celsius to liquid at 0 degrees Celsius?
80cal/g
Would thermal energy be greater at 0 degrees Celsius or 48 degrees Fahrenheit?
Thermal energy is a measure of the internal energy of a system and is not dependent on the unit of temperature used. Therefore, the thermal energy at 0 degrees Celsius would be the same as at 48 degrees Fahrenheit.
What temperature is absolute zero in degrees Celsius?
Absolute zero is -273.15 degrees Celsius. At this temperature, particles have minimum movement and energy.
How cold is absolute zero in Celsius?
Absolute zero is -273.15 degrees Celsius and -459.7 degrees Fahrenheit. Kelvin = degrees Celsius + 273.15
Is 2 degrees Celsius colder than 6?
Yes, 2 degrees Celsius is colder than 6 degrees Celsius. The numerical value of the temperature indicates the amount of heat energy present, so a lower number represents a lower temperature. In this case, 2 degrees Celsius is 4 degrees lower than 6 degrees Celsius.
What does -270 degrees Celsius mean?
(-270) degrees Celsius = (-454) degrees Fahrenheit
Is heat is measured in degrees Celsius?
Heat itself is not measured in degrees Celsius; rather, temperature is measured in degrees Celsius. Heat is a form of energy that is transferred between objects or systems due to a temperature difference. The SI unit for heat energy is the joule (J), while the SI unit for temperature is the degree Celsius (°C).
Which has more heat one liter of liquid at 80 degrees Celsius or a ten liter container at 80 degrees Celsius?
The ten liter container at 80 degrees Celsius would have more heat because it has a higher thermal capacity due to its larger volume. Heat is directly proportional to the amount of substance present, so a larger container will contain more heat energy.
