The arrangement of element in the modern periodic table is based on metalic and non metallic element
Answer:
d. 26.0 km
Explanation:
If the temperature in the region increases with depth by about 25 °C /km, then at a depth of 2 km the temperature would be 50 °C higher, at a depth of 3 km the temperature would be 75 °C higher and so on.
<u>The only way for finding melted quartz would be if the temperature is at least 650 °C.</u>
- Temperature = 25 °C /km * Depth
We put the data given by the problem and <u>solve for Depth</u>:
- 650 °C = 25 °C /km * Depth
Answer: Temperature is an example of a quantitative variable
Explanation:
A quantitative variable is defined as :
- A variable that can assume a numerical value .
- It can be ordered with respect to either magnitude or dimensions.
- It is further classified into two types : interval scale and ratio scale.
Temperature comes under interval scale , because interval scale has no zero point.
For example : A 0° C Celsius does not interpret that there is no temperature.
Therefore , Temperature is an example of a quantitative variable.
Hence, the correct answer is "quantitative variable"
Answer:
less neutral
Explanation:
A solution with pH 5 is less neutral than a solution with pH 7 because pH 5 is acid
