1. Explain, “in details,” why ice floats. In most cases, solids are denser than liquids, especially if it is the same substance, forcing it to sink. In the case of ice and water, it is the opposite. Ice has a lesser dense than water. Objects float when it has a lesser dense than the liquid it is sitting in. Ice is less denser than water because water has 2 Hydrogen atoms and 1 Oxygen atom. According to the University of York, when water freezes the molecules come close together and form strong bonds
a piece of paper on top of the cup so that the paper covers the cup at the edges and is not much bigger that the surface of the cup. Turn the cup and paper upside down (practice over the sink first) and hold the bottom of the cup (now on the top). Why doesn't the water fall out of the cup? The downward pressure on the paper by the water inside the cup is less than the upward pressure exerted by the air outside. This occurs because the pocket of space between the bottom (top of inverted glass)
together are more tightly packed together than the atoms in another object. Why do some objects float while others sink? Objects that float have a density of less than 1g/ml. Objects that have a density of more than 1g/ml will not float and thus sink in water. If an object, however has a density of exactly 1g/ml than the object would suspend or float freely in water. Boats are really heavy, why do they float? Boats float on account of buoyancy. Buoyancy, which is commonly referred to as upthrust
A body floats in a liquid only when the weight of the body is equal to the upthrust acting on it. This is called principle of floatation. It can also be applied in gas. It can only be applied in liquid. # Force and Pressure Force
of the questions imposed, which include; what is water? , when do we need it? , and why is it important? In the discussion part of this paper I will introduce the category by giving a brief explanation of what water is and the various purposes it serves in our day-to-day lives. In the analysis part of this paper one two topics will be chosen from the questions and elaborated on. The subject matters will be why is water important and the struggles we face with water today such as pollution and excessive
answer. In the poem Birches by Robert Frost a man uses imagination to better understand his hopes and dreams. In the poem the speaker is describing how branches of birch trees look after cold rain “Loaded with ice a sunny winter morning”. The speaker says the branches are weighed down by the ice and bend down but he likes to imagine they bend because “some boy’s been swinging them”. The speaker imagines this most likely because he yearns to be care free and young again. He also says that the broken
online articles The Impacts of Sexual Assault on Women by Cameron Boyd and Effects of Sexual Assault by RAINN, Rape, Abuse, and Incest National Network. What is the answer to why men, and even boys, treat girls and women the way they do, and how many rapes go unreported each year? What psychological effects does it have, as well as why do people, witnesses as well as victims, not speak out? Rape
INTRODUCTION Geophysical surveys have been used to identify the internal structure of the earth. Seismology is important for the study of the earth's interior because their resolving power is superior to that of other geophysical methods. This is because it provides depth, P-wave and S-wave propagation and velocities which are the basis for models for physical and chemical properties of each layer within the earth. (Stein, 2009) From geophysical surveys it has been found out that there are compositionally
