well, first of all you would need to know what the raft is being made of. take wood for an example. so you need to list the physical and chemical properties of wood. physical properties can be observed or measured. so one physical property of wood might be it's volume, or it's state, or it's strength, or it's hardness, or many other things that can be measured or observed. next you need to find the wood's chemical properties a chemical property describes how a substance changes into a new substance, either by combining with other elements or by breaking apart into new substances. so a chemical property of wood might be it's flammability, or it's reactivity.

Is hammering wood together to build a playhouse a chemical change or a physical change?
Hammering wood together to build a playhouse is a physical change. The wood is still wood, but its form and structure are being altered by the physical force of hammering. No new substances are being formed in this process.
Is hammering wood together a chemical or physical property?
is hammering wood togehter to build a playhouse a physical change or a cemical change
What is a physical build?
Physical build is basically your muscles and if your a female the elastin in your breasts
Is it okay to make a new weapon and write a magazine describing how to build it?
No
What physical properties would you use to find the right materials to build a birdhouse?
Resistant to bending. Good binding. Resistance to combustion. Style. Cheap.
Is producing something new a physical or a chemical change?
That depends on your definition of producing something new. If you cut lumber to build a table ... you have produced something new, but that is a physical change. Wood is still wood. But if you mean combining two or more substances, like hydrogen gas and oxygen gas, and, after burning, you form water, then that is a chemical change.
Is build a jigsaw puzzle is it physical change?
yes it is a physical change!
What All of the following are ways in which sedimentary rocks form EXCEPT A. Lava cooling B. Physical processes C. Chemical processes D. Build up of plant and animal remains?
A. Lava cooling. Sedimentary rocks are formed through the accumulation and cementation of sediments through physical or chemical processes, or by the build-up of plant and animal remains. Lava cooling forms igneous rocks, not sedimentary rocks.
Is build a jigsaw puzzle a physical change?
yes it is a physical change!
Is splitting water through electrolysis into O2 and H2 gasses a physical or chemical change?
In a way it is both physical and chemical, because a chemical change is changing how the molecule is "built," while a physical change is the transformation from one form to the other. I would consider splitting water through electrolysis as a chemical change at first because physical change is keeping the build of a molecule the same while it's form changes. You could also say that the splitting itself occurs first, meaning chemical change first occurs. Physical change would the occur later because the points of physical forms change based on the atom or molecule. The time difference in which occurs first would be very hard to measure, down to nanoseconds, but according to common scientific sense chemical change would occur first. The true answer to this question would be that it is chemical change, because you wanted to know what the splitting part was. Hope this helps!
What is a chemical which plants build up?
cellulose
What are the issues in physical design?
