Note that the given constant is not a specific heat capacity constant, it's the heat capacity of the block in Joules per degree Kelvin. As such you do not need the mass as it's already taken into account (think of it as being the specific heat of the substance multiplied by the mass of the block). The constant would apply to this block and this block only.RabbitWho said:A metal block of heat capacity 60 J K -1 loses 1MJ of heat energy
Is the given constant 60 or 600 J/K ? You have 60 in the problem statement... Ah, I can see that if the answer is 1667 C that "600" is the correct value.RabbitWho said:OK so 600JK -1 (600 joules per kilo per Kelvin) is necessary to change the temperature by `
1 MJ of heat is lost...
Is that 1 megajoules ? so that is 1 million joules?
The answer at the back says that the change in temperature is 1667 degrees Celsius.. I am sorry I can't see how to get that answer
The formula for finding the mass of a metal block with heat capacity 60JK is mass = heat capacity/ specific heat capacity.
The unit of measurement for heat capacity is Joules per Kelvin (JK).
Heat capacity is directly proportional to the mass of a metal block. This means that as the heat capacity increases, the mass also increases.
No, the mass of a metal block cannot be negative. Heat capacity is a physical property that represents the amount of energy needed to raise the temperature of a substance, and mass cannot have a negative value.
Yes, there are several methods for measuring the mass of a metal block with heat capacity 60JK. One common method is to use a balance scale, where the mass of the metal block is compared to known masses until they are balanced. Another method is to use the density and volume of the metal block to calculate its mass.
