How much would the freezing point of water decrease if 4 mol of sugar was added to 1 kg of water?
The freezing point depression constant for water is approximately 1.858°C kg/mol. Using the formula ∆Tf = iKfm, where i is the van't Hoff factor, Kf is the freezing point depression constant, and m is the molality, we can calculate the change in freezing point. In this case, with 4 mol of sugar added to 1 kg of water (1000 g), the molality is 4 mol / 1000 g = 4 m/kg. Plugging these values in, we get ∆Tf = 1 * 1.858 * 4 = 7.432°C. The freezing point of water would decrease by 7.432°C.
Which temperature would be more comfortable for most people 80 Fahrenheit or 80 celsius?
Most people would find 80 Fahrenheit more comfortable than 80 Celsius. 80 Fahrenheit is approximately 27 degrees Celsius, which is a more moderate and comfortable temperature for most individuals.
To convert 29 degrees Fahrenheit to Celsius, you can use the formula: Celsius = (Fahrenheit - 32) x 5/9. Plugging in the value 29 for Fahrenheit gives: Celsius = (29 - 32) x 5/9 = -2.78 degrees Celsius.
What is 11 degrees Fahrenheit in centigrade?
11 degrees Fahrenheit is equal to a temperature of -11.67 degrees Celsius.
How would you abbreviate a rectal temperature of 99.7 degrees F?
The rectal temperature of 99.7 degrees Fahrenheit could be abbreviated as 99.7°F.
Can humans survive at 55 degrees Celsius?
Human survival at 55 degrees Celsius is unlikely without proper precautions and adaptations. Prolonged exposure to such high temperatures can lead to heat stroke, dehydration, and organ damage. It is essential to seek shade, stay hydrated, and avoid physical exertion to prevent heat-related illnesses.
What temperature is six degrees less than two degrees celsius?
Four degrees Celsius. Subtracting six from two degrees Celsius gives four degrees Celsius.
Why doesn't the temperature increase as the liquid changes into a gas?
During phase change from liquid to gas, the energy is used to break the intermolecular forces holding the liquid together rather than increase the temperature. This energy is called latent heat and is used to overcome the forces between molecules instead of raising the temperature. Once all the liquid has evaporated, then additional energy will go towards increasing the temperature of the gas.
What layer of the earth is 4400-6100 degrees Celsius?
The layer that reaches temperatures between 4400-6100 degrees Celsius is the inner core of the Earth. It is a solid layer made mainly of iron and nickel and is the hottest part of our planet.
What is 38.0 Celsius to Fahrenheit?
F = 1.8 C + 32
Where F is the temperature in degree Fahrenheit, and C is the temperature in degrees Celsius.
If C = 38 then:
F = 1.8 * 38 + 32
= 68.4 + 32
= 100.4 degrees Fahrenheit
What is minus 16 c to degrees?
To convert Celsius to Fahrenheit, use the formula: °F = (°C * 9/5) + 32. Substituting -16 for °C: (-16°C * 9/5) + 32 = 3.2°F. Thus, -16°C is equal to 3.2°F.
What tool do you use to measure how hot water is?
A thermometer is used to measure the temperature of hot water.
To convert 30 degrees Fahrenheit to Celsius, you can use the formula: (°F - 32) x 5/9 = °C. Plugging in 30 for °F, the conversion is: (30 - 32) x 5/9 = -1.1°C. Therefore, 30°F is equal to approximately -1.1°C.
Yes, 34 degrees Fahrenheit is considered cold as it is below the freezing point of water (32°F). It is typically jacket weather and can feel chilly, especially if there is wind or precipitation.
What is 11 degrees Fahrenheit to Celsius?
11 degrees Fahrenheit is approximately -11.7 degrees Celsius.
How many Celsius is Minus 12 Fahrenheit?
Minus 12 Fahrenheit is approximately -24.44 degrees Celsius. This can be calculated using the formula: Celsius = (Fahrenheit - 32) / 1.8.
