How many calories of heat are required to raise the temperature of 650g of water from 13.0 C to 20.0 C?

ΔH = cmΔT

The change in heat = change in temperature (degrees C) . volume of the liquid (l) . heat capacity of the liquid

ΔH = 4.18 . 0.65 . 7

ΔH = 19kJ of heat

1 Calorie = 4.184 kJ

so 4.55 Calories are needed to heat 650g of water from 13°C to 20°C

but as some heat will be lost to the environment and there will be some incomplete combustion so you will need to burn more to see that actual change in temperature.

What temp is 25 degrees F in celsius?

Conversion from Fahrenheit to Celsius is done in three steps:

1. Subtract 32 from value in degrees Fahrenheit.

2. Multiply result of step 1 by 5.

3. Divide result of step 2 by 9.

Conversion formula: [°C] = ([°F] - 32) * 5 / 9 = (25 - 32) * 5 / 9 = -3.8888 °C

What is the equivalent of -148 'f in 'c?

(-148) degrees Fahrenheit = (-100) degrees Celsius.

[°C] = ([°F] − 32) × 5⁄9

Why we cannot you use your hand to measure temperature?

You cannot use laboratory thermometer to measure human body temp because of its markings. It is designed to measure large scale temperatures and therefore it may be hard to read the exact bocy temperature.

What is room temp water?

Room temperature water is water that has been allowed to reach the temperature of the surrounding room, generally around 68-77°F (20-25°C). It is neither hot nor cold, making it comfortable for drinking or cooking.

What is meant by freezing temperature of platinum?

The freezing point of water is 32 degrees Fahrenheit. This is equal to 0 degrees Celsius. The freezing point of platinum is 3,214.9 degrees Fahrenheit, which is equal to 1,768.3 degrees Celsius.

What is the temperature of a beaker of boiling water water?

it doesn't change, as all of the energy is used to convert the water into gas, so the temperature stays ata a constant 100 until all of the water has evaporated

What is the melting temperature for mozzarella?

Cheese has various percentages of water. I suspect that cheeses have their own particular melting and boiling points depending on what kind. You should measure it. It's probably 100C plus a bit.

Will temperature rise if it's hot?

No, the temperature will not rise if it's already hot. Temperature is a measure of the intensity of heat present in a substance, so if it's already hot, the temperature will remain constant until there is a change in the heat input or output.

What is the formula for converting temperature to millivolt?

The formula for converting temperature to millivolts varies depending on the sensor or device being used. Typically, it involves using a linear equation specific to the sensor's characteristics. It is best to consult the sensor's datasheet or manual for the exact formula to convert temperature readings to millivolts.

What is 52F equal in Celsius?

Conversion from Fahrenheit to Celsius is done in three steps:

1. Subtract 32 from value in degrees Fahrenheit.

2. Multiply result of step 1 by 5.

3. Divide result of step 2 by 9.

Conversion formula: [°C] = ([°F] - 32) * 5 / 9 = (52 - 32) * 5 / 9 = 11.1111 °C

What is 375 degree c in Fahrenheit?

Conversion from Celsius to Fahrenheit is done in three steps:

1. Multiply value in degrees Celsius by 9.

2. Divide result of step 1 by 5.

3. Add 32 to result of step 2.

Conversion formula: [°F] = [°C] * 9 / 5 + 32 = 375 * 9 / 5 + 32 = 707 °F

What is 23C convert to F?

23 degrees Celsius is 73.4 degrees Fahrenheit.

How much heat in kJ is required to melt 54.0 g ice at 0 degrees C into water at 0 degrees C if Hfus for water equals 6.01 kJ mol?

The heat required to melt 1 mol of ice is 6.01 kJ, which is equivalent to 18 g of ice. Since you have 54.0 g of ice, which is 3 times the amount in 1 mol, you would need 3 times the heat, totaling 18.03 kJ to melt the ice.

What is 365 degrees Fahrenheit equal to in degrees Celsius?

Conversion from Fahrenheit to Celsius is done in three steps:

1. Subtract 32 from value in degrees Fahrenheit.

2. Multiply result of step 1 by 5.

3. Divide result of step 2 by 9.

Conversion formula: [°C] = ([°F] - 32) * 5 / 9 = (365 - 32) * 5 / 9 = 185 °C

What is 6.9 Celsius in Fahrenheit?

Conversion from Celsius to Fahrenheit is done in three steps:

1. Multiply value in degrees Celsius by 9.

2. Divide result of step 1 by 5.

3. Add 32 to result of step 2.

Conversion formula: [°F] = [°C] * 9 / 5 + 32 = 6.9 * 9 / 5 + 32 = 44.42 °F

What is used to measure the temperature of the Earth?

The temperature of the Earth can be measured using various instruments like thermometers, satellites, and weather stations. These tools collect data from different parts of the Earth to monitor and analyze temperature changes over time.

What 7 degrees below0?

Seven degrees below 0 is -7 degrees.

Which is cooler -26 centigrade or -16 centigrade?

-26 degrees Celsius is cooler than -16 degrees Celsius.

What is 800 degrees Celsius inFahrenheit?

800 degrees Celsius = 1,472 degrees Fahrenheit.

What is the likely source for organisms that grew best at 37 degrees?

Organisms that grow best at 37 degrees Celsius are likely to be mesophiles, which are organisms that thrive at moderate temperatures. They usually come from environments that are warm, like the human body, as 37 degrees is close to human body temperature.

What is volume occupied by 30lb of Cl2 at 743 mm Hg and 70 degree F?

Some conversion required.

30 pounds Cl2 (454 grams/1 pound) = 13620 grams Cl2

13620 grams Cl2 (1 mole Cl2/70.9 grams) = 192.1 moles Cl2

70o F = 21.1o C = 294.3 Kelvin

use,

PV = nRT

(743 mm Hg)(X Volume) = (192.1 moles Cl2)(62.36 L*torr/mol*K)(294.3 K)

Volume = 3525524.47/743

= 4.7 X 103 Liters of chlorine gas
