19,212 Questions

How are melting and freezing points similar in a chemical?

Melting and freezing points are both physical properties of a substance related to its phase change from solid to liquid (melting) or liquid to solid (freezing) at a specific temperature. These points are the same temperature for a pure substance under constant pressure and can be used to identify and characterize substances.

How do you convert temperature from Kelvin to Fahrenheit?

You can use this equation to convert Kelvin to degrees Fahrenheit: [°F] = (K × 1.8) - 459.67

What is absolute zero Celsius?

Absolute zero Celsius is the lowest temperature possible on the Celsius scale, at which point particles have minimal energy and movement ceases. It is equivalent to -273.15 degrees Celsius.

What is the temperature of a freezer in fahrenheit?

If u take out the plug and hold the door open, as hot qs the surrounding air

How does temperature influence mold growth?

Temperature influences mold growth by affecting the rate at which molds can reproduce and spread. Warmer temperatures typically promote faster mold growth, while cooler temperatures can slow down or inhibit mold growth. The ideal temperature range for mold growth is between 77-86°F (25-30°C).

Is celsius in reference to heat?

Celsius is a unit of temperature measurement based on the Celsius scale, which is commonly used in many countries around the world. It is not specific to heat alone but can be used to measure the temperature of any substance or environment.

What is 600 Fahrenheit in centigrade?

600 degrees Fahrenheit is equal to 315.56 degrees Celsius.

What is the temperature of a meteriod?

The temperature of a meteoroid can vary greatly depending on its distance from the sun and its size. In space, the temperature can be extremely low, near absolute zero. However, when a meteoroid enters Earth's atmosphere, friction with air molecules can cause it to heat up rapidly, sometimes reaching temperatures exceeding 3,000 degrees Fahrenheit.

What is the answer to 78 in celsius?

78 degrees Fahrenheit is equal to about 25.56 degrees Celsius.

What is 95 f in Celsius?

The correct spelling is Celsius.

95ºF = 35ºC

What is the temp of boiling point?

The boiling point of pure water at sea level is 100 degrees Celsius or 212 degrees Fahrenheit.

What is negative 87 degrees celsius in Fahrenheit?

Conversion formula: [°F] = [°C] * 9 / 5 + 32 = -87 * 9 / 5 + 32 = -124.6 °F

Which is colder 10celsius or 45f?

10c= 50f

or

45f = 7.2C

so 10c is colder!

What is absolute zero in psi?

Absolute zero in psi refers to a theoretical temperature at which particles have minimal kinetic energy. It is equivalent to -459.67°F or 0 psi. At this temperature, molecular motion ceases, making it the lowest possible temperature in the Kelvin scale.

What is 175 degrees in celsius?

175 degrees Fahrenheit is equal to 79.44 degrees Celsius.

What is the Celsius freezing temperature?

The Celsius freezing temperature is 0 degrees Celsius. At this temperature, water freezes and turns into ice.

What are the signs that a liquid has reached its boiling point?

Oh come one -_-''

Its obvious

  • Bubbles of vaporised liquid will form
  • The temperature of the liquid when boiling will remain constant even when more heat is applied.
  • As the liquid is heated, the vapour pressure increases until it equals the pressure of the gas above it.

If water freezes at 273 Kelvin and 32 F and it boils at 373 K and 212 F how do you solve for the linear relationship between the Kelvin and Fahrenheit temperature scales?


For Kelvin as measure of temperature interval (and not specific temperature):

(373 - 273) Kelvins (K) = (212 - 32) F 0

or,

for 1 Kelvin temperature interval,

1 K = 1.8 F o (for temperature interval)

As specific temperature,

K = C o + 273.16 ...... (1)


and

C 0 = (F o - 32) x 5/9 ...(2)

Then, substitute for C o from eq 2 in 1 :

K = (F o - 32) x 5/9 + 273.16

or

K = F o x 5/9 + 255.382 (for specific temperature)

What is 84 degrees Fahrenheit in Kelvins?


C o = ( F o - 32 ) x 5/9

Where F o is degrees Fahrenheit and C o degrees Celsius

Kelvins = C o + 273.16

Accordingly,

84 degrees Fahrenheit = (84 - 32 ) x 5/9 = 28.89 degrees Celsius

28.889 degrees Celsius = 28.89 + 273.16 = 302.05 Kelvins

Answer 84 degrees Fahrenheit = 302.05 Kelvins

What is the temperature of absolute 0?

Absolute Zero is a theoretical temperature where all molecular activity ceases and by international agreement it is set at -273.15 Celsius.

What is the energy required to heat 25 gallons of water from 20 degrees Celsius to 80 degrees Celsius?

Rather than do the math for you I will lay out how to do it and you can do the numbers yourself.

First, convert the volume of 25 gallons to milliliters:
Volume (gal) -> Volume (mL)


Second find the change in temperature:
T(high) - T(low) = dT (oC)


The calorie is defined as the amount of energy to raise one gram of water 1 degree Celsius.


Energy (calories) = Mass of Water (g) * dT (oC)


to find the mass of water convert volume to mass using the density equation D= m/V


Volume (mL) * Density (g/mL) = Mass of Water (g)


So the required energy is simply:


E (cal) =mass*dT


If you must report your answer in Joules (customary) you can convert calories to Joules using an established conversion constant.


E (cal) -> E (J)

What is -170C in Fahrenheit?

-170C X 9 = -1530.

-1530/5 = -306.

-306 + 32 = -274.

-274F = -170C.

I hope this helps. If you look at my equation you can use the steps I have written to figure out and temperature.

What is the conversion of -10 degrees celsius to fahrenheit?

-10ºC = 14ºF

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

How many liters would a 20 liter sample of gas at stp occupy if the pressure was changed to 20 atmospheres and the temperature was changed to 38 c?

P1V1/T1 = P2V2/T2

Change all temps to Kelvin. ( 38 C + 273.15 = 311.15 K and 25 C = 298.15 K )

(1 atm)(20 L)/(298.15 K) = (20 atm)(X L)/(311.15 K)

5963X = 6223

X = 1.0 Liters
