How much joules does it take to heat water to 100 degrees?

To heat 1 gram of water by 1 degree Celsius, it takes 4.18 joules. So, to heat water from, for example, 20 degrees to 100 degrees, you would need to calculate the total mass of water and apply the specific heat capacity to determine the total energy required.

Which is hotter 100 degrees of Celsius or 100 degrees of Fahrenheit?

Celsius

100 degrees Celsius is equal to 212 degrees Fahrenheit

What is 228 degrees celsius in Fahrenheit?

228 °F is equal to about 108.9°C

The conversion formula is Celsius temperature = 5/9 x (Fahrenheit temperature - 32)

You subtract 32, multiply by 5, and divide by 9. In this instance, 228 degrees Fahrenheit is equal to 228 - 32 = 196 x 5 = 980/9 = 108.88 (repeating)

Which phases of a substance can exist when the pressure is less than the pressure of the triple point?

When the pressure is less than the pressure of the triple point, the substance can exist in the solid and gas phases. At pressures below the triple point pressure, the substance cannot exist in the liquid phase.

Why do they have different surface temperature?

Planets have different surface temperatures due to various factors such as their distance from the sun, composition of their atmosphere, and presence of natural processes like volcanism or greenhouse gases. These factors can affect the amount of incoming solar radiation absorbed by the planet, how that heat is distributed, and how much of it is retained, leading to differences in temperature across different planets.

Why isn't the freezing point of a liquid a chemical property?

Because when something freezes, the atoms and molecules don't undergo a chemical change, they go through a physical change. By this, I mean that the individual atoms and molecules lose kinetic energy (energy that makes you move) in order to freeze. There is no chemical change here. Rather, the molecules and atoms are slowing down physically.

What is 60-degrees ferinheight in Celsius?

60°F = 15.6°C

  • (60°F - 32) multiplied by 5/9 = 15.6°C

How many reference temperature points are needed to create a thermometer scale?

Two reference temperature points are needed to create a thermometer scale. These points are used to calibrate the scale and typically consist of the freezing and boiling points of a substance, such as water.

What characteristics must a liquid have before it can be used in a thermometer?

One thermometric property that is required is that it must vary linearly with temperature. In liquid-in-glass thermometers, the length of the liquid thread is often used to determine temperature. Thus when temperature increases, the liquid must expand uniformly with temperature, so that it can be used to measure temperature accurately.

What element has the highest melting point magnesium silicon or chlorine?

The element with the highest melting point is silicon. Silicon has a melting point of 1414°C, while magnesium melts at 650°C and chlorine is a gas at room temperature.

Convert 25 kelvins to degrees celsius?

The answer is 248.15 K (approx.). The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively. To convert from C to K, add 273.15 to C.

What is the density of air at 15 degrees?

The density of air at 15 degrees Celsius is approximately 1.225 kg/m^3 at standard atmospheric pressure. This value can vary slightly depending on factors such as humidity and elevation.

What is 103 deg Fahrenheit in Celsius?

103 degrees Fahrenheit is equal to 39.4 degrees Celsius. The formula to convert Fahrenheit to Celsius is (Fahrenheit - 32) x 5/9.

What is equivalent to 88 Fahrenheit?

88 Fahrenheit is equivalent to approximately 31 degrees Celsius.

What does -270 degrees Celsius mean?

(-270) degrees Celsius = (-454) degrees Fahrenheit

Does 139 Celsius mean its cold?

no... 139 Celsius is above the boiling point of water.

What is modified rankine cycle?

modified rankine

cycle basically same as rankine

cycle but main difference is inisentropic

expansion process.we

are nt

expanding the styeam

completely.steam is expanded up to certain level and after that it dumped in condenser

due to high vacuum in condenser.the

work losses by restricting the expansion

of steam is very less which can be neglected.so

that the stroke length of

cylinder is reduced and the capitalcost

of engine also reduced.engine

performance is also good

How much is negative 30 celsius in Fahrenheit?

Negative 30 degrees Celsius is equal to -22 degrees Fahrenheit.

How do you convert fifty five degrees celsius into Fahrenheit?

Use this formula for converting Celsius to Fahrenheit: (C x 1.8) + 32 = F

  • 55 x 1.8 = 99
  • 99 + 32 = 131
    • 55 degrees Celsius = 131 degrees Fahrenheit.

What was the boiling point of water as measured using the römer temperature scale?

The boiling point of water on the Römer temperature scale is 60 degrees. Römer scale was developed by René Antoine Ferchault de Réaumur where 0 degree is freezing point and 80 degree is boiling point of water.

How do you turn Celsius from Fahrenheit?

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and then multiply by 5/9. The formula is: Celsius = (Fahrenheit - 32) * 5/9.

Is water boils at 100 degrees celsius?

Water does boil at 100 celsius. However evaporation occurs at any temperature. so for boiling to occur a specific temperature is required which it is called the boiling point of that substance whereas evaporation occurs at any temperature Water only boils at the temperature of 100 degrees Celsius at standard atmospheric pressure. So up a mountain, where the air pressure is reduced, water boils at a lower temperature. Water boils at sea level at 100 degrees Celsius

Why can't you iron wet clothes?

An Iron works by heating the fibres of the cloth to above 100 degrees Celsius. As water boils at 100 degrees Celsius, it is impossible to get the fibres of the cloth to above 100 degrees Celsius when they are wet and therefore wet clothes can not be ironed effectively.

You may note that some Irons use steam. In this case the steam is above 100 degrees Celsius and the sole plate of the iron is even hotter. The steam aids the ironing process by 1) taking the heat into the fibres and 2) softening the fibres so that they can be flattened more easily.
