How much heat in KJ must be transffered to 10kg of air to increase the temp from 10 Celsius to 230 Celsius at the pressure constant?

The specific heat capacity of air at constant pressure is 1.005 kJ/kg°C. The heat transferred can be calculated using the formula Q = m * c * ΔT, where Q is the heat transferred, m is the mass of the air, c is the specific heat capacity of air, and ΔT is the change in temperature. Plugging in the values, Q = 10 kg * 1.005 kJ/kg°C * (230°C - 10°C) = 4,550 kJ.

How do you convert 22 c to k?

To convert from degrees Celsius (°C) to Kelvin (K), you simply add 273.15 to the temperature in Celsius. In this case, 22°C + 273.15 = 295.15 K. Therefore, 22°C is equivalent to 295.15 K.

What is negative 1.6 degrees Celsius equal to?

Negative 1.6 degrees Celsius is equal to 29.12 degrees Fahrenheit.

What is 129 degrees F in C?

129 degrees Fahrenheit = 53.9 degrees Celsius

[°C] = ([°F] − 32) × 5⁄9

How can water be made to boil at 90 degrees celsius?

Water boils at 100 degrees Celsius at standard atmospheric pressure. To make water boil at 90 degrees Celsius, you would need to increase the pressure acting on the water. This can be achieved in a pressure cooker or by pressurizing the system. At higher pressures, the boiling point of water increases.

What is 100000 kelvin in degrees C?

Remember 0 oC = 273K

and 100 oC = 373K

So subtract 273 from 100,000K = 99727oC

What is 100 in Celsius?

The boiling point of water under normal atmospheric conditions.

Compare boiling point of water on kelvin and celsius scale?

The boiling point of water is 100 degrees Celsius, which is equivalent to 373.15 Kelvin. The Kelvin scale starts at absolute zero, where there is no molecular motion, while the Celsius scale starts at the freezing point of water.

How cold is a freezer in Celsius?

A typical freezer is set to maintain a temperature of 0 degrees Celsius or below, typically around -18 degrees Celsius. This temperature is ideal for safely storing frozen foods for an extended period.

What is the temperature -3 Celsius expressed in kelvins?

The temperature -3 degrees Celsius is equivalent to 270 kelvins. To convert from Celsius to kelvin, you simply add 273.

What is 1115 celsius converted into Fahrenheit?

1115 degrees Celsius is equal to 2039 degrees Fahrenheit.

How do you convert 32 k into celsius degress?

To convert from Kelvin to Celsius, you simply subtract 273.15 from the temperature in Kelvin. Therefore, to convert 32 K to Celsius, you would subtract 273.15 from 32 K to get approximately -241.15°C.

How much is 310 Fahrenheit in Celsius?

310 degrees Fahrenheit is equal to 154.44 degrees Celsius.

Does table sugar melt at 186 degrees celsius?

No, table sugar (sucrose) does not melt at 186 degrees Celsius. Sucrose melts at around 186 degrees Celsius and breaks down into glucose and fructose at higher temperatures.

What does -3 celsius mean in Fahrenheit?

-3 degrees Celsius is equivalent to 26.6 degrees Fahrenheit. This can be calculated using the formula: F = (C x 9/5) + 32.

How much energy is released when 42.5g of aluminum vapor are cooled from 4750 degrees Celsius to 25 degrees Celsius?

The amount of energy released during a cooling process can be calculated using the formula: Q = mcΔT, where Q is the heat released, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. Given that the specific heat capacity of aluminum is 0.897 J/g°C, and the overall temperature change is 4725°C (4750 - 25), we can calculate the energy released. Plugging the values into the formula: Q = 42.5g * 0.897 J/g°C * 4725°C = 180,288.75 Joules.

What temperature scale useds the abbreviation k?

The Kelvin scale uses the abbreviation K. It is a unit of temperature measurement based on the thermodynamic temperature scale, in which 0 K represents absolute zero, the absence of all thermal energy.

What temperature is negative 2 degrees c?

Negative 2 degrees Celsius is below freezing point, which is 0 degrees Celsius. It is a cold temperature that can lead to frost formation and icy conditions.

What is 56 degrees Fahrenheit convert to in celsius?

56 degrees Fahrenheit is equivalent to approximately 13.33 degrees Celsius.

What is a word for maintain a constant temperature?

"Regulate" is a word that can be used to describe maintaining a constant temperature.

What is 451 Fahrenheit in Celsius?

451 degrees Fahrenheit is equal to approximately 232.78 degrees Celsius. You can convert Fahrenheit to Celsius using the formula: Celsius = (Fahrenheit - 32) * 5/9.

What is the state of rubidium when room temperature is at 25 degrees celsius?

Rubidium is a solid at room temperature (25 degrees Celsius). It has a melting point of 39.3 degrees Celsius, so at 25 degrees Celsius, rubidium would be in its solid state.

How can you make water boil at a higher temp than 100 C?

By increasing the pressure on the water, you can raise its boiling point above 100°C. This can be achieved in a pressure cooker, where the increased pressure allows the water to reach a higher temperature before boiling.

How much heat is released when 160 grams of steam at 100 degrees C liquefies?

The heat released when steam at 100 degrees Celsius condenses into liquid water is equal to the heat it absorbed during the phase change from liquid water to steam. This heat is known as the latent heat of vaporization, which for water is approximately 2260 J/g. Therefore, the amount of heat released when 160 grams of steam liquefies is approximately 160g x 2260 J/g = 361,600 J.
