Chemistry
___________________is anything that has mass and takes up space.
Matter
Carbon dioxide + water + Sunlight -------> glucose + oxygen
Photosynthesis
How does a substance change from a solid to a liquid?
Evaporation
Give the UNIT that is used to measure the volume of the object above
cm3 (centimeters cubed)
C6H12O6 + ? -------> C02 + H20
O2
In a solid, the __________________ are in fixed positions and cannot move away from one another.
particles
Calculate the volume of the object with L=4cm, w=5cm and h=7cm. (Include the formula for volume)
v = l x w x h
4 x 5 x 7 = 140cm3
What effect does increasing the light have on the rate of photosynthesis?
increases the rate of photosynthesis until it reaches its limit
Neither liquids nor solids can be __________________, bus gases can.
compressed
describe how to measure the volume of an irregular object like a rock or stone.
To measure the volume of an irregular object like a stone using a graduated cylinder and overflow can, follow these steps: Fill the graduated cylinder with water and record the initial volume. Carefully place the stone into the cylinder, ensuring no water spills. The water level will rise. Record the new water level, noting the meniscus. Subtract the initial volume from the final volume to find the stone's volume. For example, if the initial water volume was 50 mL and the final volume with the stone was 75 mL, the stone's volume would be 25 mL.
Is photosynthesis an example of a CHEMICAL change or a PHYSICAL change and why?
Chemical - it makes new substances
The force of gravity created by an object is affected by two main factors. Name/Describe one of them.
Respiration....
releases energy from food
