Question | Answer |
Triple beam balance | Measures the mass of an object. |
Graduated cylinder | Measures volume of an object. |
Flask | Holds or mixes chemicals. |
Were your safety googles when: | When working with heat, working with chemicals or tour teacher tells you to. |
Most important safety rule: | Listen to your teacher and follow all instructions very carefully. |
D=M/V | Formula to find density. Density=mass/volume |
Chemical change | Chemical reaction takes place, the object becomes a whole new material with new and different properties. |
Chemical change indicators | color change, gas produced, solid precipitate produced, heat or light produced and temperature absorbed. |
Physical change | are changes affecting the form of the object, but the object still the same. |
Parts of an atom and its charge | Protons(positive charge), neutrons(no charge, electrons(negative charge)and electron shells. |
The periodic table is arrange by... | increasing atomic number. |
Chemical equations | A way of describing a chemical reaction. |
Balanced force | All forces acting on an oject are equal, and causes no change. |
Unbalanced force | All forces acting on the object aren't equal, there will be a change in motion. |
Newton's 1st law | An oject at rest remains at rest, and an oject in motion remains in motion with the same speed and direction. |
Newton's 2nd law | Acceleration of an object depends on the mass of the object and the amount of force applied to the object. |
Newton's 3rd law | for every action, there is an equal and opposite reaction. |
S=D/T | Formula to find speed. Speed=Distance/Time |
Same distance, more time in a speed graph. | No movement. |
Same speed, more time in a acceleration graph. | Constant speed. |
