- A partially filled one-gallon [gal] pitcher, that has a mass of 0.35 kilograms [kg] when empty, is sitting on a kitchen counter. Assume the total mass of the pitcher and its contents is 2 kilograms [kg]. The pitcher contains a liquid that has a molecular weight of 19.5 grams per mole [(g)/(mol)] and a molarity of 57 moles per liter [(mol)/(L)]. (a) Determine the volume of the liquid in the pitcher in units of liters [L]. (b) Determine the specific gravity of the liquid in the pitcher.Describe the differences between gravity and vacuum filtration.A small amount of resin weighing 4.56g occupies a height of a 10mL graduated cylinder equivalent to one mL.

Calculate the time taken by him to climb the height of 20m.Bobby Drake aka “Iceman” is member of the X-Men who has the physics-defying ability to “manipulate cold and ice.” Iceman is depicted with the ability to lower the temperature of nearby objects at will. For example, Iceman can freeze an entire pond in seconds just by touching the surface of the water. Let’s put some numbers to this example: The pond is 20 m across and can be approximated as a hemisphere. You can assume the density of water is 1.00 g cm–3 and independent of temperature. The temperature of the pond is initially 17°C and uniform throughout. After Iceman freezes the pond, its temperature is –10°C a) How many moles of water are in the pond? b) What is the total amount of heat removed from the pond?Bobby Drake aka “Iceman” is member of the X-Men who has the physics-defying ability to “manipulate cold and ice.” Iceman is depicted with the ability to lower the temperature of nearby objects at will.

Calculate the slope of the plot of distance against time, and give its units.A U-shaped tube containing an amount of mercury. The left arm of the tube has cross-sectional area A1 of 10.9 cm2, and the right arm has a cross-sectional area A2 of 5.40 cm2. In both arms, the mercury is at the same level, as shown. In the second one, 300 g of water is poured into the right arm of the tube and sits atop the mercury, all of it within the right arm. The mercury level in the right arm has been displaced downward, and the mercury level in the left arm has been displaced upward from its original level by a distance h. The density of mercury is 13.6 g/cm3, and the density of water is 1.00 g/cm3.
