Matter is anything that has and takes up
In the Metric System the base unit for mass is , the base unit for distance is , the base unit for is liter and the base unit for is second.
In the Metric System, the prefix is used for .000001
1 cubic centimeter is the same as 1 .
is an indication of how close a measurement is to the true value.
Precision is an indication of the on the measuring device that was used.
Significant figures are important because they tell us about the
accuracy of the measurements used.
precision of the measurements used.
When using scientific notation there
can be as many numbers to the left of the decimal point as your calculator indicated
should be no numbers to the left of the decimal point
should have all the numbers to the left of the decimal point
should have one digit on the left side of the decimal point
In chemistry, the greek character rho is used to stand for
Density is mass per unit
Energy is defined as the ability to do .
Work is the force applied to an object times the that the object travels parallel to that force
Two kinds of energy are , or stored energy and , or energy in motion.
In order to arrive at a scientific law, first a person observes, then forms a , then tests the hypothesis with . After being confirmed by rigorous experimentation, the hypothesis is considered a . A theory that is continuously confirmed by observation becomes a scientific .
Three temperature scales are commonly used. is commonly used by the public in the United States. , or centigrade, is a metric unit, and , often called the absolute temperature scale, is used for very cold temperatures.
To convert Celsius to Fahrenheit, we use the formula °F= ( / ) (°C) + .
To convert Celsius to Kelvin, we use the formula, K = °C +
1 = 4.184 Joules
Specific heat is the amount of necessary to raise the temperature of 1 of a substance by degree Celsius.
Temperature change in an object is related to the amount of heat it absorbs or releases by the equation: =∆T
The equation tells us that any heat by the calorimeter and the water must have been by the object placed in the calorimeter.
