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

What is K equals 98.6 degrees Fahrenheit?

A temperature of 98.6 degrees Fahrenheit is equivalent to a human body temperature typically considered as normal. It is often used as a reference point in medical contexts for measuring fevers or changes in body temperature.

What is the kelvin number for daylight?

Daylight typically has a color temperature ranging from 5000 to 6500 Kelvin, with midday sunlight around 5500K.

What is 650 celsius to Fahrenheit?

650 degrees Celsius is equivalent to 1202 degrees Fahrenheit.

What was a problem with early attempts to measure temperature?

Early attempts to measure temperature faced challenges due to inconsistent standards and lack of universally accepted scales. Instruments like the mercury thermometer were limited by inaccuracies in calibration and variations in manufacturing. Additionally, the lack of standardized references made it difficult to compare temperature measurements across different instruments and locations.

What temperature equals zero celsius?

The temperature that equals zero degrees Celsius is equivalent to 273.15 Kelvin.

What is 55 degrees F converted to Celsius?

55 degrees Fahrenheit is approximately 12.8 degrees Celsius. To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and then multiply by 5/9.

What is -224 degrees celsius in fahrenheit?

-224 degrees Celsius is equal to -371.2 degrees Fahrenheit using the formula (C × 9/5) + 32 = F.

What is -224 degrees C in the temperature F?

The following equation is used for the conversion:

[oF] = [oC] x 9/5 + 32

So -224 oC = -371.2 oF

What is 165 fahrenheit in degrees?

165 degrees Fahrenheit is equivalent to approximately 74 degrees Celsius.

How much energy is needed to change 125g of ice at -32.9 degrees to water at 75 degrees?

To calculate the energy needed to change ice at -32.9 degrees to water at 75 degrees, you need to consider the energy required for three steps:

  1. Heating ice from -32.9 degrees to 0 degrees (specific heat capacity of ice)
  2. Melting ice at 0 degrees into water at 0 degrees (latent heat of fusion of ice)
  3. Heating water from 0 degrees to 75 degrees (specific heat capacity of water)

Once you have the energy needed for each step, you can add them together to find the total energy required.

What happens when a metal heated at 280 degree celsius is immureg in water?

In that case, the metal will cool down, and the water will heat up. Also, since the temperature difference is quite big, the water will form lots of bubbles, and make a lot of noise, because of the sudden heating.

What is the temperature when boiling water starts to evaporate?

There is no such temperature to start evaporating. Even in the room temperature or in a refrigerator, water does evaporate. When a particular water molecule absorbs adequate energy (let's say from heat), there will be a phasechange in that molecule from liquid to gas, and it's called evaporation.

What is the temperature of a soda if you put it in ice for 30 mins?

The temperature of the soda will decrease due to the ice's lower temperature, but it will not reach the same temperature as the ice. The rate of cooling will depend on various factors such as the initial temperature of the soda, the amount of ice, and the thermal conductivity of the container.

Which solid is the most soluble at lower temperatures than at higher temperatures?

In general, most solids are more soluble at higher temperatures than at lower temperatures. However, there are exceptions such as cerium sulfate, which follows the opposite trend and is more soluble at lower temperatures than at higher temperatures.

What is the specific heat capacity 0f 50 grames solid at 80 degrees Celsius put in water of 100 grames at 25 degrees Celsius if final temperature of both was 30 degrees Celsius?

Two q's to 0. q = mass * specific heat * change in temp.. Q falls out of equation

(50 g)(X specific heat)(30 C - 80 C) + (100 g H2O)(4.180 J/gC)(30 C - 25 C) = 0

(- 2500X) + (2090) = 0

- 2500X = - 2090

X = 0.836 J/gC

=============the specific heat of the solid

What is 425 K in degrees Fahrenheit?

425 K - 273.15

= 151.85o Celsius

===============now,

Temperature Fahrenheit = (151.85o C)(1.80) + 32

= 305.33o Fahrenheit
