Using the ideal gas law equation, PV = nRT, we can find the number of moles of gas. First, convert the temperature to Kelvin (95+273 = 368 K) and the volume to liters (263 mL = 0.263 L). Then, plug in the values and solve for n. n = (748 mmHg * 0.263 L) / (0.0821 L atm/mol K * 368 K). Finally, calculate n to find the moles of gas in the flask.
What is the method to find Fahrenheit?
F to C: Deduct 32, then multiply by 5, then divide by 9
C to F: Multiply by 9, then divide by 5, then add 32
What are the instruments used to measure temperature of cells?
Common instruments used to measure the temperature of cells include thermometers, thermocouples, infrared thermometers, and thermal imaging cameras. These instruments can provide accurate temperature readings in various settings, from laboratory experiments to industrial applications.
Why did the reaction not proceed at all at 100 degree celsium?
The reaction may not have proceeded at 100 degrees Celsius because the temperature was too high, causing the reactants to decompose or the reaction to reach an equilibrium where the rate of the forward reaction is equal to the rate of the reverse reaction, resulting in no net change in the concentrations of the reactants and products. It's also possible that the reaction requires a lower temperature for activation energy to be met.
To convert Celsius to Kelvin, add 273.15, so -100C = 173.15K. To convert Celsius to Fahrenheit, multiply by five-ninths and add 32, so the answer is -148.
What to wear at 0 degrees celsius?
At 0 degrees Celsius, it is important to wear warm clothing such as layers, a thick winter coat, hat, gloves, scarf, thermal socks, and insulated boots to stay warm and protect yourself from the cold. Be sure to also wear water-resistant and windproof materials to stay dry and shielded from harsh weather conditions.
What is the temperature reached in a sandwich toaster?
Hot enough to begin caramelizing the starch in bread, which happens when the starches get to about 310° Fahrenheit. Because the heating elements are not right up against the bread, and because there is air circulation inside a toaster, the heating elements themselves, made of nickel-chromium alloy, can reach 1100-1200°F.
How do you convert 225 degrees celsius to Fahrenheit?
Use this formula to convert degrees Celsius/Centigrade (ºC) to degrees Fahrenheit (ºF): (ºC x 1.8) + 32 = ºF
Is degree celsius a unit of mass?
Because every object has mass but the metric unit of measure is grams
What star has a temperature in the 3000 degrees?
It is a main sequence star of class M. It can range in size form 0.08 to 0.45 solar masses, and a radius of less than 0.7 times that of the sun. A majority (76%) of main sequence stars belong to this category.
What does 76 degrees Fahrenheit convert to in celsius?
76°F = 24.4°C (76°F - 32) multiplied by 5/9 = 24.4°C
6750 J
What is 150 degrees Fahrenheit closest to in degrees Celsius?
150 degrees Fahrenheit is closest to 65.6 degrees Celsius when converted.
Does salt affect the temperature of water -boiling point - freezing point?
i would opt for the Freezing point. salt decreases the freezing point of water. so if water would normally freeze at 0C, saltwater would freeze at -3C.
How do you convert 37 Celsius to Fahrenheit?
F to C: Deduct 32, then multiply by 5, then divide by 9
C to F: Multiply by 9, then divide by 5, then add 32
98.6 F
What should you wear in 19-degrees celsius?
In 19 degrees Celsius weather, you can wear a lightweight jacket, jeans or pants, and a long-sleeve shirt or sweater. Add a scarf or hat for extra warmth if needed. It's a good idea to wear layers so you can adjust to changing temperatures throughout the day.
Why does a beach ball shrink while in a freezer?
According to Charles's Law, temperature and volume are proportional; that is, as temperature increases, volume increases by the same factor, and vice versa. Thus, as the temperature of the air inside the beach ball decreases, its volume decreases as well.
Is 72 degrees warm enough to wear shorts?
It depends on the individual and their comfort level with the weather. 72 degrees Fahrenheit is generally considered warm enough for most people to wear shorts comfortably, but some may still find it a bit cool. Ultimately, it's a personal preference.
