After ice melts into liquid water, you can refreeze it into solid ice if the temperature drops. Freezing and melting are physical changes.
Answer:
chemical change changes the identity of a substance, while a physical change can just be observed. Some signs that a chemical change has occurred are, temperature change, forming bubbles, color change, new substance forming, there are more, but those are just some of which i now

describe how and where carbondioxide enters the leafe?
Answer:Carbon dioxide cannot pass through the protective waxy layer covering the leaf (cuticle), but it can enter the leaf through an opening (the stoma; plural = stomata; Greek for hole) flanked by two guard cells. Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata.
Explanation:
How can you tell the difference between alternate and opposite leaf arrangements?
They are based on based whether the leaf pinnate or palmate venation.
They are based on based whether the leaf has one or two leaves at the node.
They are based on based whether the leaf has a smooth or toothed margin.
They are based on whether the leaf is simple or compound.
Answer:
They are based on based whether the leaf has one or two leaves at the node.
Explanation:
Answer: They are based on based whether the leaf has one or two leaves at the node.
Explanation: You can tell the difference between alternate and opposite leaf arrangements based on whether the leaf has one or two leaves at the node. Alternate leaf arrangement is when a single leaf is attached at one location on the stem, the node, in an alternating pattern. On the other hand, the opposite leaf arrangement is when two leaves are attached to the same node on opposite sides of the stem.
Question: Characteristics of styrofoam cup before placing it in water
Subject: Science
Styrofoam cups are utensils made of polystyrene foam that are used for drinking purposes. The physical properties of the cups before placing in water are firm and hard in shape.
What are physical characteristics?Physical characteristics are the properties that are not manifested by the chemical reactions and include the measurable and visible state, including conductivity, hardness, solubility, shape, malleability, melting points, color, etc.
Styrofoam cups are thermoplastic which allows them to remain solid at RT and liquid at the boiling point. They can be arranged and molded into various shapes and sizes according to the need.
The cups are stiffer and stronger before they are placed in water, but after they are placed in water they lose their firmness and become soft.
Therefore, the styrofoam cups are solids and a little firm before placing in water.
