The specific heat of a certain type of cooking oil is 1.75 cal(g and middot and degC). How much heat energy is needed to raise the temperature of 2.40 kg of this oil from 23 and degC to 191 and degC?
The change in temperature is ΔT = 191°C - 23°C = 168°C. The heat energy Q required is given by the formula Q = mcΔT, where m is the mass, c is the specific heat, and ΔT is the temperature change. Plugging in the values: Q = 2.4 kg * 1.75 cal/(g°C) * 168°C = 7056 cal = 7.056 kcal.
How much heat is needed to raise the temperature of 6.00 g of copper by 15.0 and degC?
The specific heat capacity of copper is 0.385 J/g°C. Using the formula Q = mcΔT, where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the temperature change, you can calculate that 34.65 J of heat is needed to raise the temperature of 6.00 g of copper by 15.0°C.
How can one determine the change in temperature?
To determine the change in temperature, you can subtract the initial temperature from the final temperature. This will give you the difference in temperature, showing how much the temperature has changed.
What amount of heat needed to increase the temperature of a 1-kilogram substance by 1 and degC is known as the?
The amount of heat needed to increase the temperature of a 1-kilogram substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is a measure of how much heat energy is required to raise the temperature of a given mass of the substance by one degree Celsius.
Molten iron is extremely hot averaging about 1500 The specific heat of iron is 0.46 How much heat is released to the atmosphere when 1 molten iron cools to room temperature?
0.46 * 1475 = 678.5 Kjoules (The specific heat is given in terms of joules/ gramme/degC, whilst the question refers to 1kg ie 1000g )
Does molecular speed change as much as the temperature?
It changes in proportion to the temperature change.
The specific heat of a certain type of cooking oil is 1.75 cal(g and middot and degC). How much heat energy is needed to raise the temperature of 2.40 kg of this oil from 23 and degC to 191 and degC?
The change in temperature is ΔT = 191°C - 23°C = 168°C. The heat energy Q required is given by the formula Q = mcΔT, where m is the mass, c is the specific heat, and ΔT is the temperature change. Plugging in the values: Q = 2.4 kg * 1.75 cal/(g°C) * 168°C = 7056 cal = 7.056 kcal.
If the temperature changes by K by how much does it change in Celsius?
A change of 1 Kelvin is exactly the same as a change of 1 Celsius degree.
What is the coefficient of expansion of diesel oil that is how much will it expand and contract in volume with changes in temperature assume for this question you are only speaking of liquid diesel?
Automotive diesel: 0.00084 per degC i.e. 10degC increase will produce roughly 1% increase in volume The figure varies for other hydrocarbons, but most are between 0.0007 and 0.0012 per degC.
If the temperature changes by 100k by how much does it change in celsius?
To convert kelvin to celsius, you need to subtract 273.15 from the temperature in kelvin. Therefore, a change of 100K is equivalent to a change of 100°C in celsius.
Why is mercury used in a thermometer why not green water?
Water does not change as much in volume with temperature as much as Mercury does, which makes it more difficult to read temperature Changes on a scale.
How much does the velocity of sound changes for every 1 degree change in temperature?
0.61 meters a second
whose body temperature does not change much even when the temperature of the environment changes is called?
Animals whose body temperatures do not change much despite the temperature of the environment changing are called ectotherms. This ability allows some animals to live in harsh environments.
If the temperature changes by 100 K how much does it change in celsius?
100 degrees. The increments in both scales are identical.
If the temperature changes by K by how much does it change in degrees Celsius?
convert 68 fahrenheit to celsius. (celsius =(fehrenhit -32)/ 1.8)
Does the Viscosity changes with the temp and pressure?
The viscosity of a substance will change with both temperature and pressure. For liquids the changes induced by a change in temperature are usually more readily observed than the changes from pressure because liquids are only slightly compressible with pressure. In gasses, the changes in viscosity with pressure are much more easily demonstrated because gases are, almost by definition, quite compressible so that the density can be easily changed by either changes in pressure or changes in temperature.
Water temperature changes as much as atmospheric temperature?
false
