EBK CHEMISTRY: ATOMS FIRST
- Convert the following temperatures to degrees Celsiusor Fahrenheit: (a) 95°F, the temperature on a hotsummer day; (b) 12°F, the temperature on a cold winterday; (c) a 102°F fever; (d) a furnace operating at1852°F; (e) −273.15°C (theoretically the lowestattainable temperature).arrow_forwardAfter sitting on a shelf for a while, a can of soda at a room temperature (69°F) is placed inside a refrigerator and slowly cools. The temperature of the refrigerator is 37°F. Newton's Law of Cooling explains that the temperature of the can of soda will decrease proportionally to the difference between the temperature of the can of soda and the temperature of the refrigerator, as given by the formula below: T = Ta + (To – Ta)e¬kt the temperature surrounding the object To = the initial temperature of the object t = the time in minutes the temperature of the object after t minutes k = decay constant T The can of soda reaches the temperature of 54°F after 40 minutes. Using this information, find the value of k, to the nearest thousandth. Use the resulting equation to determine the Fahrenheit temperature of the can of soda, to the nearest degree, after 95 minutes. Enter only the final temperature into the input box.arrow_forward(a) Normally the human body can endure a temperatureof 105°F for only short periods of time without permanentdamage to the brain and other vital organs. What is thistemperature in degrees Celsius? (b) Ethylene glycol isa liquid organic compound that is used as an antifreezein car radiators. It freezes at −11.5°C. Calculate itsfreezing temperature in degrees Fahrenheit. (c) Thetemperature on the surface of the sun is about 6300°C.What is this temperature in degrees Fahrenheit?arrow_forward
- Expressing amounts of energy in different energy units is necessary to solve many chemistry problems. For practice, complete the following table. The Joule (J) is the SI unit of energy. 1 calorie (cal) = 4.184 J; 1 kcal = 1000 calarrow_forward(4) The normal melting point of gold is 1064.5 °C and its boiling point is 2660 °C. (a) Convert these two values to the Fahrenheit and Kelvin scales. (b) Find the difference between those two values in Celsius. (c) Repeat (b) using the Kelvin scale. (6) The Eiffel tower is built from iron and it is about 324 m high. Its coefficient of linear expansion is approximately 12 x 10-6 (C°)¯l and assumed constant. What is the increase in the tower's length when the temperature changes from 0°C in winter to 30°C?arrow_forward7. State whether each of the following represents a chemical change or merely a physical change:(a) A few grams of sucrose (table sugar) are placed in a small beaker of deionized water; the sugar crystals “disappear,” and the liquid in the beaker remains clear and colorless.(b) A copper statue, over time, turns green.(c) When a teaspoon of baking soda (sodium bicarbonate) is placed into a few ounces of vinegar (acetic acid), volumes of bubbles (effervescence) are produced.arrow_forward
- Light travels in a vacuum at a speed of 3.00 × 108 m s-1 .(a) Convert this speed to miles per second.(b) Express this speed in furlongs per fortnight, a littleused unit of speed. (A furlong, a distance used in horse racing, is 660 ft; a fortnight is exactly 2 weeks.)arrow_forwardA metal object of an irregular shape has a mass of 31.5 grams. When the metal is added to water in a graduated cylinder, the volume of water increases from 5.28 mL to 7.61 mL. (A) How much water does the metal displace? (B) Calculate the density of the metal. (C) Is the metal made of platinum? Explain. (Hint: the density of platinum = 21.4 g/cm³)arrow_forwardContainer A and Container B were filled completely with chicken powder. The total mass of 1/3 of the chicken powder in Container B and 1/11 of the chicken powder in Container A was 570 g. If 5/11 of the chicken powder in Container A was poured out, the total mass of the chicken powder in both containers became 2.28 kg. How much chicken powder was in (a) Container A in grams? (b) Container B in grams?arrow_forward
- Expressing amounts of energy in different energy units is necessary to solve many chemistry problems. For practice, complete the following table. The Joule (J) is the SI unit of energy. The calorie (cal) is the amount of energy needed to raise the temperature of 1 g of water by 1°C, 1 cal = 4.184) The British Thermal Unit (BTU) is the amount of energy needed to raise the temperature of 1 pound of water by 1°F. 1 BTU - 1055J BTU 7.67 kJ 0.463 kcal 0.181arrow_forwardCalculate the quantity of heat required to raise the temperature of 20.0 g of water from 19.1 °C to 30.6 °C. Calculate the final temperature, in degrees Celcius, when 85.0 g of water, initially at 21.7 °C, absorbs 4.41×103 J of heat. °C (do not include the temperature unit in your response as it is already specified)arrow_forwardDimensional Analysis is a way of doing numerical "book-keeping" when converting quantities or performing calculations. • When converting quantities from one unit to another, conversion factors are used. Solving with Dimensional Analysis and Multiple Units: If I am in Canada where the price of gas is $1.022 USD·L1, how much will it cost me to fill up my gas tank if I travelled 125 km? • Let's also assume that my car gets an average of 30.0 miles/gallon.arrow_forward
