Which of the following formulas expresses the relationship between the pressure and absolute temperature of a gas sample whose volume is fixed? The basketball moves off in the original direction of the bowling ball, B. faster than v while the bowling ball continues slower than v, A rocket is fired in space. If the cart covers 100 m in 30 s, the force the horse exerts on the cart is, A sedentary person requires about 6 million J of energy per day. When an additional gram of air is pumped into the container and there is no change in temperature, the new pressure is, The pressure on 100 liters of helium is increased from 100 kPa to 400 kPa. 6789 Quail Hill Pkwy, Suite 211 Irvine CA 92603. The specific heat capacity of a substance is the amount of heat that needs to be supplied to a unit mass of that substance to raise its temperature through 1° Celsius or Kelvin. The average pressure of the atmosphere at sea level corresponds to which one or more of the following? The specific heat capacity has units of J/gºC. This rate of energy consumption is equivalent to about, The KE of a 900-kg car whose speed is 60 km/h is, A 1-kg mass has a KE of 1 J when its speed is, A 1-N weight has a KE of 1 J when its speed is, The speed of a 1000-kg car whose KE IS 450 kJ is, A 1-N weiht has a PE relative to the ground of 1 J when it is a height of, A horizontal force is applied to a 2-kg ball on a smooth table. The following ScienceStruck article will cover some information related to metalloids. ? what happens when radium-226 is converted to radon-222. The specific heat of water is 4.184 J/g ºC. Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3.Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. As it moves, the total momentum of the rocket and its exhaust gasses, To prevent it from tumbling in flight, a projectile such as a football is sent off spinning. Its freezing point is, The first law of thermodynamics is the same as the, In order to operate, a heat engine must have. The maximum possible efficiency of a heat engine. To double its kinetic energy, its speed should be increased to approximately, A total of 4900 J is expended in lifting a 50-kg mass, The mass is raised to a height of, The height above the ground of a child on a swing varies from 0.5 m at the lowest point to 2.0 m at the highest point. A. the vaporization of a solid without first becoming a liquid. We also use third-party cookies that help us analyze and understand how you use this website. Which is correct? The properties of several different materials are being compared. If the average speed of the hydrogen molecules was originally v, their new average speed is, In order to double the average energy of the molecules in a gas at 200 K, its temperature must be changed to, Fifty kJ of heat is added to a 10-kg piece of lead at its melting point of 330°C and 2 kg of lead melts. The specific heat capacity ($$c$$) of a substance, commonly called its specific heat, is the quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius (or 1 kelvin): $c = \dfrac{q}{m\Delta T} \label{12.3.4}$ Specific heat capacity depends only on the kind of substance absorbing or releasing heat. At which of the following Celsius temperatures will a Fahrenheit thermometer show the same reading in degrees? The new volume of the helium is, An absolute temperature of 100 K is the same as a Celsius temperature of, One liter of hydrogen gas at atmospheric pressure is allowed to expand to a volume of 3 liters with the temperature held constant. D. depends on the ratio between the exhaust and intake temperatures. Since heat capacities of compounds are not constants, you will need to refer a table of measured specific heat capacities of a substance at different temperatures, if necessary.
