How much does wood expand with changes in temperature eg a 50cm oak plank going from 20C to 30C under constant humidity?
Under constant humidity wood won't expand much from 20c to 30c. Moisture is the leading cause of expansion in wood products.
For an exact answer you'll need to specify with the grain or against it.
You can then use the coefficients located here

0.0000030 (across grain)
0.0000027 (parallel to grain)
put them into the calculator located here

Which give the following answer
0.015 millimeters across grain
0.0243 millimeters Parallel to grain

How does Charles' Law work to explain the relationship between the volume and temperature of a gas at constant pressure?
Charles' Law states that the volume of a gas is directly proportional to its temperature when pressure is held constant. This means that as the temperature of a gas increases, its volume also increases, and vice versa. The law helps to explain how gases expand or contract with changes in temperature while keeping pressure constant.
Do liquids expand and contract at the same rate?
No, liquids do not expand and contract at the same rate. Different liquids have different coefficients of expansion, which determine how much they expand or contract with changes in temperature. This property is important when designing systems where temperature changes may affect the volume of the liquid.
Does glass break or crack with temperature changes?
When temperatures changes this can cause the molecules in an object to contract [ at low temperatures ] or to expand [ high temperatures ] . Glass is a fragile object and if the molecules in glass contract or expand quickly this can cause the glass to break . [SRM] .
What is the effect of varying the temperature on the volume of a constant mass of a gas at a constant pressure?
the relation is given by charles law which says that the volume of a constant mass of gas at constant pressure is directly proportional to the temperature so increase in temperature causes an increASE in the volume
What gases expand?
All gases can and will expand in the right conditions.
When does wood expand and contract?
Wood expands and contracts in response to changes in temperature and humidity.
How much does oak expand and contract with changes in humidity?

How does wood expand and contract with changes in temperature and humidity?
Wood expands and contracts with changes in temperature and humidity due to the absorption and release of moisture. When the air is humid, wood absorbs moisture and swells, causing it to expand. Conversely, in dry conditions, wood releases moisture and contracts, leading to shrinkage. This natural process can cause warping, cracking, or splitting in wood structures.
Why do they leave a gap between the flooboards and the wall?
So that the floorboards can expand and shrink as humidity and/or temperature changes. If they were right up against the wall, any expansion could lead to buckling.
How does pine wood react to changes in humidity and temperature, specifically in terms of warping?
Pine wood is sensitive to changes in humidity and temperature, which can cause it to warp. When exposed to high humidity, pine wood can absorb moisture and expand, leading to warping. Conversely, in dry conditions, pine wood can lose moisture and shrink, also causing warping. It is important to properly store and maintain pine wood to minimize the risk of warping.

Is it possible for a balloon with an initial pressure of 200.0kPa to naturally expand four times its initial volume when the temperature remains constant and atmospheric pressure is 101.3kPa?
No, it is not possible for the balloon to naturally expand four times its initial volume while the temperature remains constant. According to Boyle's Law, at constant temperature, the pressure and volume of a gas are inversely proportional. Since the atmospheric pressure remains constant, the balloon's pressure of 200.0kPa would need to increase to expand, which cannot happen at constant temperature.
Why is my electric guitar bridge lifting up?
Your electric guitar bridge may be lifting up due to changes in temperature and humidity causing the wood to expand and contract, or due to the tension of the strings pulling on the bridge.
How does high altitude air density change when near the equator where there are large temperature and humidity swings?
High altitude air density near the equator tends to be lower due to the warmer temperatures causing air to expand, reducing its density. Additionally, high humidity can further decrease air density as water vapor molecules displace nitrogen and oxygen molecules in the atmosphere. These large temperature and humidity swings at the equator can result in more dynamic changes in air density compared to other regions.
What do changes in temperature cause rock to do?
Changes in temperature cause rock to expand and contract. This may cause them to crack, and pieces may break off.
Do liquids expand and contract at the same rate?
No, liquids do not expand and contract at the same rate. Different liquids have different coefficients of expansion, which determine how much they expand or contract with changes in temperature. This property is important when designing systems where temperature changes may affect the volume of the liquid.
How does Charles' Law work in relation to the behavior of gases?
Charles' Law states that the volume of a gas is directly proportional to its temperature, assuming pressure remains constant. As the temperature of a gas increases, its volume also increases, and vice versa. This law helps explain how gases expand and contract with changes in temperature.
