![Q = 10.4 \; \text{kJ}](https://tex.z-dn.net/?f=%20Q%20%3D%2010.4%20%5C%3B%20%5Ctext%7BkJ%7D%20)
The specific heat of a material gives the energy it takes to increase the temperature of one unit mass of the material by one unit temperature. The SI unit for specific heat
is therefore
.
The formula relating the energy required to raise the temperature of
grams of a substance with specific energy
by
degrees is
![Q= c \cdot m \cdot \Delta T](https://tex.z-dn.net/?f=%20Q%3D%20c%20%5Ccdot%20m%20%5Ccdot%20%5CDelta%20T%20)
The question provides the following information:
Apply the formula:
![\begin{array}{ccc} Q & = & c \cdot m \cdot \Delta T\\ & = & 130 \; \text{J} \cdot \text{kg}^{-1} \cdot \textdegree{\text{C}}^{-1} \times 1 \; \text{kg} \times 80 \; \textdegree{\text{C}}\\ & = & 1.04 \times 10^{4} \;\text{J}\\ & = & 10.4 \; \text {kJ} \end{array}](https://tex.z-dn.net/?f=%20%5Cbegin%7Barray%7D%7Bccc%7D%20Q%20%26%20%3D%20%26%20c%20%5Ccdot%20m%20%5Ccdot%20%5CDelta%20T%5C%5C%20%20%26%20%3D%20%26%20130%20%5C%3B%20%5Ctext%7BJ%7D%20%5Ccdot%20%5Ctext%7Bkg%7D%5E%7B-1%7D%20%5Ccdot%20%5Ctextdegree%7B%5Ctext%7BC%7D%7D%5E%7B-1%7D%20%5Ctimes%201%20%5C%3B%20%5Ctext%7Bkg%7D%20%5Ctimes%2080%20%5C%3B%20%20%5Ctextdegree%7B%5Ctext%7BC%7D%7D%5C%5C%20%26%20%3D%20%26%201.04%20%5Ctimes%2010%5E%7B4%7D%20%5C%3B%5Ctext%7BJ%7D%5C%5C%20%26%20%3D%20%26%2010.4%20%5C%3B%20%5Ctext%20%7BkJ%7D%20%5Cend%7Barray%7D%20%20)

The metric system is used because it is based on the number 10. Ten is easy to use for mathematical operations and conversions.
It is also easy to use for scientific notation when you are referring to powers of ten. There are extremely large and extremely small numbers in science. Thus, scientific notation allows for accurate abbreviated ways to symbolize these numbers. For instance, if I were to say 1,000, in scientific notation it would be 1 x 10 ^3. If I was to say 1,000,000, I would scientifically write 1 x 10 ^6.
If Gold's natural state has a definite shape and a definite volume, then its natural state is solid.
