How much heat is required to raise the temperature of 0.25 kg of water from 20C to 30C?
The specific heat capacity of water is 4.18 J/g°C. To raise the temperature of 0.25 kg (250 g) of water by 10°C, you would use the equation Q = m * c * ΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Thus, Q = 250g * 4.18 J/g°C * 10°C = 10450 Joules.
When the temperature cools to 1000 degrees Celsius, the water vapor molecules lose energy and slow down, eventually condensing into liquid water droplets as they reach their saturation point. This process is known as condensation.
Liquid helium has a boiling point of 4.2 k What is that in Celsius?
4.2 Kelvin is -268.95 degrees Celsius.
It is very cold because water freezes at 32 degrees Fahrenheit
What is 62.6 Fahrenheit in Celsius?
Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32
In this case, the answer is about 143.6 degrees Fahrenheit.
What phase is water at 150 degrees celsius?
That depends upon the air pressure around the water. At one atmosphere, the average air pressure at sea level on Earth, it would be a gas.
Yes, but this is only caused by difference in effect of evaporation during cooling or warming up. It costs energy to evaporate and that is mainly acquired from the liquid, so stimulating the cooling (faster) and counteracting at warming up (slower).
33.7 degrees celsius is 92.66 degrees fahrenheit.
33.7 degrees fahrenheit is 0.94 degrees celsius.
Which temperature scale has 100 degrees between freezing and boiling?
The Celsius temperature scale has 100 degrees between freezing and boiling.
What can be said of a boiling point of a liquid?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas. It is a characteristic property of the liquid and can be influenced by factors such as pressure and impurities in the liquid.
What is melting point of bakelite?
It doesn't have a melting point as it is a thermosetting plastic, meaning it can be heated but it will not melt, instead the temperature will be raised until it burns.
Hope this help :D
What is the temperature range on earth?
There is a great range of temperatures on Earth. These temperatures range from far be low zero to more than 100 degrees Fahrenheit just on Earth's crust.
Is 50 degrees hotter on a Celsius scale or Farenhight scale?
50 degrees is hotter on the Celsius scale.
None. Changing water from 25 degrees C to 5 degrees C requires heat to be REMOVED, not added!
How is air helpful in maintaining temperature?
Air acts as an insulator by trapping heat close to the Earth's surface through a process called the greenhouse effect. It also helps to distribute heat evenly around the planet through convection currents, moving warm air from the equator to cooler regions. Additionally, air can absorb and release heat, helping to regulate temperature fluctuations.
Why do you think increase in 9 degrees above our normal temperature has lethal effect on cells?
An increase in temperature of 9 degrees above normal can denature proteins and disrupt cellular processes in the body. This can lead to cell damage and even cell death. High temperatures can also cause enzymes to lose their shape and function, impairing essential biological reactions.
What is the Celsius temperature of 375 degrees F?
375 ºF = 190.555 ºC
190.56 Celsius.
In order to convert degrees Fahrenheit into degrees Celsius, take the number of degrees you have in Fahrenheit (in this particular scenario, 375), subtract it by 32, multiply the answer times 5, and then divide that answer by 9.
375 - 32 = 343
343 x 5 = 1715
1715 / 9 = 190.555 ~ 190.56
Conversely, to convert Celsius into Fahrenheit, you would multiply your degrees Celsius by 9, then divide by 5, and then add 32.
The Fahrenheit scale is typically utilized in the United States, whereas Celsius (part of the Metric system) is the temperature scale primarily used in most other countries.
Can mold grow at 0 degrees Fahrenheit?
Mold typically does not grow at temperatures below freezing (0 degrees Fahrenheit) because it needs moisture to thrive. While mold spores can remain dormant at very low temperatures, they usually require warmer conditions to germinate and grow.
When changing from a solid to a liquid the magic temperature for the substance is called?
The magic temperature for a substance where it changes from a solid to a liquid is known as its melting point. This is the temperature at which the solid gains enough thermal energy to overcome its attractive forces and transition into a liquid state.
Celsius (Centigrade):
80°F is approximately 26.7°C.
Kelvin:
To convert Fahrenheit to Kelvin, you can use the formula: K = (°F - 32) × 5/9 + 273.15.
So, 80°F is approximately 300.9 K.
Rankine:
The Rankine scale is an absolute temperature scale based on Fahrenheit degrees. To convert from Fahrenheit to Rankine, you can use the formula: °R = °F + 459.67.
Therefore, 80°F is exactly 539.67°R.
Reaumur:
The Reaumur scale is less commonly used, but you can convert Fahrenheit to Reaumur using the formula: °Re = (°F - 32) × 4/9.
So, 80°F is approximately 17.8°Re.
How many degrees below zero is -34 degrees Celsius?
-34 °F is equal to -36.67 °C
The conversion formula is Celsius temperature = 5/9 x (Fahrenheit temperature - 32)
What is the temperature in the sunlight zone?
The temperature in the sunlight zone can vary depending on the location and time of year, but it generally ranges from around 68°F to 104°F (20°C to 40°C). This zone receives the most sunlight and is where most marine life thrives due to the abundance of light and warmth.
Is 32 degrees Fahrenheit hot or cold?
32 degrees Fahrenheit is considered cold, as it is the freezing point of water.
