Why does water have a different boiling point at elevation than at sea level?

Water boils at a lower temperature at higher elevations because the atmospheric pressure is lower. At higher elevations, the air is thinner, so there is less pressure pushing down on the water, causing it to boil at a lower temperature.

What is 20 degree Celsius?

20 degrees Celsius is a measurement of temperature - air at 20 degrees Celsius is a comfortable temperature for people to live in. 20 degrees Celsius = 68 degrees Fahrenheit

Which elements melting point is -112 C?

The element with a melting point of -112°C is nitrogen (N).

What C does water boil under normal atmospheric pressure?

Water boils at 100 degrees Celsius under normal atmospheric pressure.

How can you convert a temperature expressed in degrees Celsius into kelvin?

To convert a temperature in degrees Celsius to Kelvin, you add 273.15 to the temperature in Celsius. This is because the Kelvin scale starts at absolute zero, which is -273.15 degrees Celsius. The formula is: K = °C + 273.15.

How many degrees Celsius is in one kelvin?

To convert kelvin to Celsius, you subtract 273.15 from the temperature in kelvin. So, 1 kelvin is -272.15 degrees Celsius.

What is true about the melting point and freezing point of water?

The melting point and freezing point of water is the same at 0 degrees Celsius (32 degrees Fahrenheit) under standard atmospheric pressure. This means that water will transition from solid to liquid (melting) or liquid to solid (freezing) at this temperature.

What is the temperature of 79 degrees celsius expressed in kelvin?

Kelvin is the SI unit for temperature. Celsius is usually used in metric systems. 0 degree celsius is 273.15 Kelvin. Kelvin increases equally with celsius. So to convert celsius to kelvin, we just add 273.15 to celsius. The answer in Kelvin is 352.15

What is the density of water at 22.9 degree celsius?

At 22 degrees Celsius the density of fresh water is 997.77 kilograms per cubic metre (kg/m3) or 0.99777 g/cm3. The SI unit for density is kilograms per cubic metre (kg/m3.

Water has roughly a density of 1000 kg/m3.

What is the value of 27 degrees Celsius on the Kelvin temperature scale?

27 degrees Celsius is equivalent to 300 Kelvin on the Kelvin temperature scale. To convert from Celsius to Kelvin, you simply add 273.

How the liquid in a thermometer change so that it can be used to measure a temperature?

The liquid in a thermometer expands and contracts as the temperature changes. This causes the liquid to rise or fall in a narrow tube connected to the bulb of the thermometer. The markings on the tube indicate the temperature based on how high or low the liquid level is.

What is the temperature -79 celsius expressed in kelvin?

The answer is 239.15 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 do degrees Celsius measure?

Degrees Celsius measure temperature. It is a unit of measurement typically used to express temperatures in the Celsius scale, which is based on the freezing and boiling points of water at sea level.

What state is chlorine in at -65 degrees celsius?

Chlorine would be in a solid state at -65 degrees Celsius. Chlorine's melting point is -101 degrees Celsius, so at -65 degrees Celsius it would exist as a solid.

How many grams of ice can be melted with 145 grams of 45 degree C H2O?

To calculate how many grams of ice can be melted by 145 grams of water at 45°C, you first need to determine how much heat is required to cool the water to 0°C and then how much heat is needed to melt the ice at 0°C. Use the specific heat capacity of water (4.18 J/g°C) and the heat of fusion of ice (334 J/g) in your calculations. The final result will be the mass of ice melted.

What is 735 in degrees celsius?

735 degrees Celsius is equivalent to 1355 degrees Fahrenheit.

What is 375 dgrees celsius in ferhanheit?

375 degree Celsius = 707 degree Fahrenheit

What is 0 celsius equal to in Fahrenheit?

0 degrees Celsius is equal to 32 degrees Fahrenheit.

What kelvin temperature corresponds to 5F?

The conversion formula from Fahrenheit to Kelvin is K = (F + 459.67) x (5/9). Plugging in 5 for F gives: K = (5 + 459.67) x (5/9) ≈ 258 K.

What is 227 kelvin in degrees celsius?

227 Kelvin is equal to -46.15 degrees Celsius.

What is the temperature scale on which water boils at 100 degrees?

Water boils at 100 degrees Celsius on the Celsius temperature scale.

What is 816 celsius in Fahrenheit?

816°C = 1500.8°F

816°C multiplied by 1.8 +32 = 1500.8°F

What is the volume of 1 gallon of cold gasoline 60 degrees F compared to warm gasoline 80 degrees F?

The volume of gasoline increases with temperature. When gasoline is warmer at 80 degrees F compared to 60 degrees F, it will expand and occupy a larger volume than the same amount of gasoline at the lower temperature.
