Is the boiling point of a pure substance the same as an impure substance and why?

Adding impurities changes both boiling points and freezing points. The added material has its own chemical interactions with the solvent to which it is added. In order to boil, a substance must overcome the chemical attraction between its own constituent atoms or molecules. If there are also other atoms or molecules to which a constituent atom or molecule of a given substance is also attracted, the boiling point will therefore be higher. No it's not the same it dip pends on what the substance is.

Convert this temperature to the Kelvin scale 146 C?

To convert 146°C to Kelvin, you need to add 273.15 to the Celsius temperature.

146°C + 273.15 = 419.15 Kelvin.

What happens when water reaches 212 degrees Fahrenheit?

Water reaches its boiling point of 212 degrees Fahrenheit at standard atmospheric pressure. At this temperature water transitions from liquid to vapor, forming steam.

What is the difference between Celsius and Fareignheight?

Celsius and Fahrenheit are two different temperature scales used to measure temperature. The main difference is that the Celsius scale sets the freezing point of water at 0 degrees and the boiling point at 100 degrees, while the Fahrenheit scale sets the freezing point of water at 32 degrees and the boiling point at 212 degrees. Additionally, the Celsius scale is more commonly used in scientific and international contexts, while Fahrenheit is more commonly used in the United States.

Why is temperature of boiling water cannot be measured using an alcohol thermometer?

Alcohol thermometers are not suitable for measuring the temperature of boiling water because alcohol has a lower boiling point than water. The alcohol inside the thermometer would evaporate before reaching the temperature of boiling water, therefore providing an inaccurate reading.

What is boiling point of stainless steel in Fahrenheit?

"Stainless steel" refers to a group of steels with similar compositions so since there are different compositions, there is not just a single boiling point that would apply to all stainless steels. A reasonable estimate that should be close enough for most purposes and most types of stainless steels would be about 5400 °F (approx. 3000 °C)

If a wire has insulation of 150 degrees Fahrenheit what is the Celsius?

To convert Fahrenheit to Celsius: (150°F - 32) x 5/9 = 65.56°C. So, if a wire has insulation of 150 degrees Fahrenheit, it is approximately 65.56 degrees Celsius.

What element is a liquid at 0 degrees in celsius?

Mercury is the element that is a liquid at 0 degrees Celsius.

What happens if you apply stain and temperature drops below recommended degrees?

If the temperature drops below the recommended range while the stain is drying, it can cause the stain to not dry properly or to dry more slowly than usual. This can result in an uneven finish, streaking, or a cloudy appearance on the surface being stained. It's important to follow the manufacturer's guidelines for temperature when applying stain to ensure the best results.

Is boiling a kettle a chemical change?

Boiling a kettle is a physical change because it is a change in state from liquid to gas without altering the chemical composition of the water. The water molecules are simply being heated to a point where they gain enough energy to overcome the intermolecular forces holding them together, turning into steam.

On which of the temperature scales does water boil at the highest numerical value?

Water boils at the highest numerical value on the Kelvin scale, at 373.15 K.

Lower part has temperatures -50 degress upper temperature are 0 degress?

The temperature range is from -50 to 0 degrees, where -50 degrees is the lower limit and 0 degrees is the upper limit. The temperature is in the negatives and ranges from extremely cold to freezing.

How much energy is required to raise the temperature of 3kg of aluminum from 18 degrees Celsius to 23 degrees Celsius?

The specific heat capacity of aluminum is 0.902 J/g°C. First, convert 3kg to grams (3000g). Then, calculate the change in temperature (23°C - 18°C = 5°C). Finally, use the formula Q = mcΔT to find the energy required: Q = 3000g * 0.902 J/g°C * 5°C.

How is the freezing point of a substance related to the melting point of the substance?

The freezing point and melting point of a substance are the same temperature but represent opposite phase transitions. The freezing point is the temperature at which a liquid turns into a solid, while the melting point is the temperature at which a solid turns into a liquid.

How much energy is needed to increase the temperature of 100kg of iron by 40 degrees?

The specific heat capacity of iron is about 0.45 J/g°C. To calculate the energy required to increase the temperature of 100kg of iron by 40 degrees, we first convert kg to grams: 100 kg = 100,000 g. Then we use the formula: Energy = mass x specific heat capacity x temperature change. Therefore, Energy = 100,000g x 0.45 J/g°C x 40°C = 1,800,000 Joules or 1.8 Megajoules.

What happens if you heat the steam above 100 degrees celsius?

If you heat steam above 100 degrees Celsius, it will continue to increase in temperature without changing to water. This is because steam is already in a gaseous state at temperatures above 100 degrees Celsius.

56 degrees f is about how many degrees c?

56 degrees Fahrenheit is approximately 13.3 degrees Celsius. To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature, then multiply by 5/9. Therefore, (56°F - 32) x 5/9 = 13.3°C.

What happens to water at negative 20 degrees Celsius?

At -20 degrees Celsius, water typically freezes and turns into solid ice. This is below the freezing point of water, which is 0 degrees Celsius.

How many degrees is 170 degrees C?

170 degrees Celsius is 338 degrees Fahrenheit.

What is methane at 25 degrees celsius?

At 25 degrees Celsius, methane exists in a gaseous state, as it has a boiling point of -161.5 degrees Celsius. It is a colorless and odorless gas that is lighter than air.

72 f to Celsius?

To convert 72°F to Celsius, subtract 32 from 72 to get 40, then multiply by 5/9 to get 22.22°C.

Negative 12 degrees Celsius is what Fahrenheit?

Negative 12 degrees Celsius is equal to approximately 10.4 degrees Fahrenheit.
