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.
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.
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.
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.
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 )
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.
The answer is 53,683 kJ.
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.
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.
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.
heat will flow from the iron to the water until both are the same temperature
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.
The specific heat of copper is 0.093 cal/g(C°) or 390 J/kg(C°).
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.
Where are you getting this specific heat number. With the other numbers there is no cancellation.
The specific heat capacity of copper is approximately 0.385 J/g°C. This means that it takes 0.385 joules of energy to raise the temperature of 1 gram of copper by 1 degree Celsius. Copper has a relatively high specific heat capacity compared to other metals.
25 degrees Celsius is typically considered comfortable or mild, but not cool. Cool temperatures are usually considered to be around 15-20 degrees Celsius.
