What else can I help you with?
When 90 kJ is removed from a 2-kg copper bar its temperature drops from 200C to 85C. The specific heat of copper is?
You are supposed to divide the energy by the product of (mass x temperature difference).
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 do you calculate the energy tyransferred when 3kg opf copper is heated from 20 degrees to 220 degrees?
To calculate the energy transferred when heating copper, you can use the formula: Energy = mass * specific heat capacity * temperature change. The specific heat capacity of copper is 0.385 J/g°C. Plugging in the values, you get: Energy = 3kg * 0.385 J/g°C * (220°C - 20°C).
What is a substance with low specific heat?
Substances with low specific heat have the ability to heat up or cool down quickly with a small amount of energy. Common examples include metals like copper and aluminum, which have low specific heat compared to substances like water.
What are the substances that has low specific heat capacity?
Substances with low specific heat capacity include metals like aluminum and copper, as well as gases like helium and hydrogen. These substances heat up and cool down quickly compared to substances with higher specific heat capacities.
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 specific heat capacity of copper sulphate?
The specific heat capacity of copper sulfate varies with temperature. At room temperature, it is approximately 0.39 J/g°C.
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.
What is the specific heat of copper ii sulfate?
The specific heat of copper(II) sulfate is approximately 0.39 J/g°C. This value represents the amount of heat required to raise the temperature of 1 gram of copper(II) sulfate by 1°C.
How much heat energy is required to raise the temperature of 0.365 of copper from 23.0 to 60.0 The specific heat of copper is 0.0920?
To calculate the heat energy required, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass of the copper (0.365 kg), c is the specific heat capacity of copper (0.0920 J/g°C), and ΔT is the change in temperature (60.0°C - 23.0°C). First, convert the mass to grams and then plug the values into the formula to find the heat energy required.
Which Has An Greater Specific Heat Water or Copper?
Water has a greater specific heat capacity than copper. This means that water can absorb more heat energy before its temperature increases compared to copper. This property of water is why it is often used as a coolant in various applications.
What is coppers specific heat?
The specific heat of copper is 0.093 cal/g(C°) or 390 J/kg(C°).
What is the Specific heat capacity for copper?
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.
Does copper have a higher specific heat than water?
The specific heat of water is 4184 J kg-1 K-1 The specific heat of copper 385 J kg-1 K-1. So the answer is no.
Aluminum has a specific heat capacity more than twice that of copper Place equal masses of aluminum and copper wire in a flame and the one to undergo the fastest increase in temperature will be?
The copper wire will undergo the fastest increase in temperature because it has a lower specific heat capacity compared to aluminum. This means copper can absorb heat more quickly and reach a higher temperature faster than aluminum when exposed to the same amount of heat.
How much heat is absorbed by 60.0 grams of copper when it is heated from 293 Kelvin to 353 kelvin?
The specific heat capacity of copper is 0.385 J/g°C. You can use the formula Q = mcΔT, where Q is the heat absorbed, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging in the values, you can calculate the heat absorbed by the copper.
Water has a temp of 4.184 and copper has a temp of 0.387. Does it takes more heat to raise the temp of the copper molecule?
These are not temperature numbers but specific heat numbers. They mean that it takes 4.184 Joules and 0.387 Joules respectively to raise water and copper of one gram by one degree celsius. So, as you can see, it takes a lot more heat to raise the temperature of water than it does of copper. Water has a very high specific heat.
