The simple (and almost correct) answer is W = (Tend - Tstart) cp m = 50 X 2.51 X 50 = 6275 J In reality the constant cp isn't really a constant. cp(300 K) is closer to 2.2 JK-1g-1 than 2.51, which gives you an integral over the temperature shift, and a value that is slightly lower htan 6275 J.

The specific heat of methanol is 2.51 J/g°C. To calculate the energy required to raise the temperature of 50g of methanol by 50°C, you can use the formula: Q = m * c * ΔT, where Q is the energy, m is the mass, c is the specific heat, and ΔT is the change in temperature. Plugging in the values, Q = 50g * 2.51 J/g°C * 50°C = 6275 Joules.

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.
Is Celsius more warm than Fahrenheit?
No, Celsius and Fahrenheit are just different scales for measuring temperature. A temperature in Celsius can be the same as, or warmer than, a temperature in Fahrenheit, depending on the specific values being compared.
What is the amount of energy needed to change the temp of a substance called?
The amount of energy needed to change the temperature of a substance is known as heat. It is measured in units such as calories or joules. It takes a specific amount of heat energy to raise the temperature of a substance by a certain number of degrees Celsius.
Do you need to wear a jacket when its 30 degrees celsius?
It depends on personal preference and the specific conditions such as humidity, wind, and sun exposure. 30 degrees Celsius is quite warm, so a jacket may not be necessary for most people in such temperatures.
If the temperature is currently 20 degrees Celsius and it decreases by 30 degrees what will the temperature be in Celsius?
If the temperature decreases by 30 degrees Celsius from 20 degrees Celsius, the new temperature will be -10 degrees Celsius.
What is the state of methanol at 25 degrees celsius?
At 25 degrees Celsius, methanol is a colorless liquid with a boiling point of 64.7 degrees Celsius. It is highly flammable and volatile at room temperature.
What temperature does liquid methanol turn to gas?
Pure Methanol has a freezing point of -97.7oC.
What is specific temperature?
Specific temperature is an amount of heat per unit mass required to raise the temperature by one degree Celsius.
Does methanol lower the freezing point?
Methanol will freeze at negative 143 (Fahrenheit)/ negative 97 (Celsius). If it is added to water (freezing point of 32*F/0*C) then it will make the water freeze at a lower temperature. So yes, methanol will lower the freezing point of any liquid that freezes at a higher temperature than methanol. But methanol cannot lower the freezing point of any liquid that will still be liquid at -143*F/-97*C.
What is the Specific gravity of gasoline vs temperature?
specific gravity of gasoline at 104 celsius
What is methanol's melting point?
Methanol's melting point is -97.6 degrees Celsius.
What is the density of methanol at 15 degrees Celsius?
The density of methanol at 15 degrees Celsius is approximately 0.7914 grams per cubic centimeter.
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.
How many joules of heat are necessary to raise temperature of 125g of copper from 25 degrees celsius to 300degrees celsius?
The answer is 53,683 kJ.
Is Celsius more warm than Fahrenheit?
No, Celsius and Fahrenheit are just different scales for measuring temperature. A temperature in Celsius can be the same as, or warmer than, a temperature in Fahrenheit, depending on the specific values being compared.
What is the Boiling point of methanol in Fahrenheit and Celsius?
Methanol has the following boiling points: 64.7°C, 338K and 148°F
What is the amount of energy needed to change the temp of a substance called?
