Answer:
Ice is the last major agent of weathering, erosion, and deposition.
Explanation:
Water often seeps into the cracks in rocks. When the temperature drops, the water in the cracks freeze and expand, causing the crack to widen. Eventually, the rock is broken into smaller pieces.
Answer:
The log will float on the water because its density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
Answer:
Explanation:
Hello,
In this case, we use the Avogadro's number to compute the molecules of C2F4 whose molar mass is 100 g/mol contained in a 485-kg sample as shown below:
Best regards,
Answer:
The Ideal Gas Law cannot be applied to liquids. The Ideal Gas Law is #PV = nRT#. That implies that #V# is a variable. But we know that a liquid has a constant volume, so the Ideal <u><em>Gas Law cannot apply to a liquid.</em></u>
Explanation:
this is my awnser soory if it was a multiple choice question plz mark brainliest
The heat required to raise the temperature of a certain mass of sample to a specific temperature change, we use the formula mCpΔT where m is mass, Cp is the specific heat of the substance and ΔT is the temperature change. In this case, we substitute and form 1.25 g x 0.057 cal/g C *20 C equal to 1.425 calories.
