suppose you want to know the amount of heat heat needed to raise the temperature of 2kg of copper by 10 degrees.what property of copper do yiu need to know?
Specific heat
the melting point of copper
the melting point of copper
To calculate the amount of heat needed to raise the temperature of a substance, you need to know its specific heat capacity (also known as specific heat). In this case, you need to know the specific heat capacity of copper.
The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of one unit of mass by one degree Celsius (or Kelvin). It can be represented by the symbol "C" and is typically measured in units of J/(kg°C) or J/(kg K).
For copper, the specific heat capacity is approximately 385 J/(kg°C) or 385 J/(kg K), depending on the units you are using.
Once you know the specific heat capacity of copper, you can use the following formula to calculate the amount of heat needed:
Q = m * C * ΔT
where:
Q is the amount of heat energy (in Joules)
m is the mass of the substance (in kg)
C is the specific heat capacity of the substance (in J/(kg°C) or J/(kg K))
ΔT is the change in temperature (in °C or K)
In this case, you want to raise the temperature of 2 kg of copper by 10 degrees. So you can substitute the values into the formula:
Q = 2 kg * 385 J/(kg°C) * 10°C
Q = 7,700 Joules
Therefore, it would require 7,700 Joules of heat energy to raise the temperature of 2 kg of copper by 10 degrees.
