How much heat is lost when a 640g piece of copper cools from 375 celsius to 26 celsius?

The heat lost can be calculated using the formula Q = mcΔT, where Q is the heat lost, m is the mass of the copper (640g), c is the specific heat capacity of copper (0.385 J/g°C), and ΔT is the change in temperature (375°C - 26°C = 349°C). Plugging in these values, the heat lost is 640g * 0.385 J/g°C * 349°C = 85,688 J or 85.7 kJ.


How much heat energy is required to raise the temperature of 0.362 kg of copper from 23.0 degrees Celsius to 60.0 degrees Celsius?

The amount of heat energy required can be calculated using the formula: Q = mcΔT. Given m = 0.362 kg, c = 390 J/kg°C for copper, and ΔT = (60.0 - 23.0) = 37.0 °C, plug these values into the formula to find the heat energy required to raise the temperature of the copper.


How many joules of heat energy are required to raise the temperature of 6 grams of copper of 100 degrees Celsius to 150 degrees Celsius?

The specific heat capacity of copper is 0.385 J/g°C. To calculate the heat energy required, you use the formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging the values in, you get Q = 6g * 0.385 J/g°C * (150°C - 100°C) = 92.4 Joules.


What is the difference between Celsius and Celsius Heat?

Celsius is a temperature scale used to measure heat, while Celsius Heat is a brand of dietary supplement that claims to boost metabolism and burn calories.


How much heat must be removed from a 200 g block of copper to lower its temperature from 150 celsius to 30 celsius?

0.385 Joules/Gram Celsius is the specific heat of copper. So, q(Joules) = mass * specific heat * change in temperature q = (200 g Cu)(0.385 J/gC)(30 C - 150 C) = - 9240 Joules -------------------------amount of heat dissipation ( answer can be positive )

If you tie piece of copper wire a end of a exhaust.. what will happen?

If a person ties a piece of copper wire at the end of the exhaust pipe on a vehicle the copper is going to heat up. When the copper heats up it will turn a rainbow of colors.


How can the copper be changed back into a solid?

Copper can be changed back into a solid by cooling it down, either by letting it reach ambient temperature or by using a cooling agent like water or liquid nitrogen to speed up the process. As copper cools down, its molecules slow and arrange themselves into a solid crystalline structure, resulting in the formation of a solid piece of copper.


What is the specific heat of copper at STP?

The specific heat of copper at standard temperature and pressure (STP) is approximately 0.385 J/g°C. This means that it requires 0.385 joules of energy to raise the temperature of 1 gram of copper by 1 degree Celsius at STP.

What is the mass in grams of a piece of copper that released 125 calories when cooled from 100 degrees Celsius to 25 point 3 degrees Celsius the specific of copper is 00924 cal per g x degrees Celsius?

Using the heat capacity of copper (0.0924 cal/g°C), you can calculate the mass of the copper using the formula q = mcΔT, where q is the heat energy (125 cal), m is the mass of the copper (in grams), c is the specific heat capacity of copper (0.0924 cal/g°C), and ΔT is the change in temperature (100-25.3 = 74.7°C). Rearranging the formula to solve for mass, you get: m = q / cΔT = 125 cal / (0.0924 cal/g°C * 74.7°C) ≈ 176.41 grams.
