What is the final temperature of a 34.2 g of water initially at 282 K that has been heated with 2.71 kJ of energy?
The final temperature of copper is
Further explanation:
The property is a unique feature of the substance that differentiates it from the other substances. It is classified into two types:
1. Intensive properties:
These are the properties that depend on the nature of the substance. These don't depend on the size of the system. Their values remain unaltered even if the system is further divided into a number of subsystems. Temperature, refractive index, concentration, pressure, and density are some of the examples of intensive properties.
2. Extensive properties:
These are the properties that depend on the amount of the substance. These are additive in nature when a single system is divided into many subsystems. Mass, enthalpy, volume, energy, size, weight, and length are some of the examples of extensive properties.
Specific heat is the amount of heat required to increase the temperature of any substance per unit mass. Specific heat capacity is also known as mass specific heat. Its SI unit is Joule (J).
The formula to calculate the heat energy of copper is as follows:
…… (1)
Here,
Q is the amount of heat transferred.
m is the mass of copper.
c is the specific heat of copper.
is the change in temperature of copper.
Rearrange equation (1) to calculate the temperature change.
…… (2)
The value of Q needs to be converted into J. The conversion factor for this is,
So the value of Q can b calculated as follows:
The value of Q is 4689 J.
The value of m is 34.2 g.
The value of c is .
Substitute these values in equation (2).
The temperature change can be calculated as follows:
…… (3)
Here,
is the change in temperature.
is the final temperature.
is the initial temperature.
Rearrange equation (3) to calculate the final temperature.
…… (4)
The value of is .
The value of is
Substitute these values in equation (4).
So the final temperature of copper is .
answer is: naturally occurring solid, inorganic compound or element is mineral.
minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
for example magnetite is a mineral of iron oxide (fe₂o₃).
calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).
dolomite is an carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
