The atmosphere inside the room has 35 mol of Co(2). The temperature decreases by 22 °C. Solve for heat (KJ). (The molar heat capacity of carbon dioxide is 37.27 J/ degree Celsius mol)

A particular container holds 3.77 mol of neon gas. The volume of this container can be altered by sliding a piston in or out. The volume is changed from 8.60 L to 12.20 L while at the same time the temperature is changed from 303 K to 345 K. The molar heat capacity, Cym, for neon is 12.47 J/(mol · K). Assume that this value will not change over the given temperature range. What is the change in entropy for the gas? AS = J/K TOOLS x10 MacBook Pro

The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temperature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. Note the difference between the terms molar heat capacity, which has units of J/(mol-K). and specific heat, which has units of J/(g-K). Remember to use 3 significant figures for all answers unless stated otherwise in the problem. Common issues with this problem involve entering units incorrectly into the answer field.

A 56.1 g sample of polystyrene, which has a specific heat capacity of 1.880 J-g °C-1 is put into a calorimeter (see sketch at right) that contains 250.0 g of water. The temperature of the water starts off at 24.0 °C. When the temperature of the water stops changing it's 29.8 °C. The pressure remains constant at 1 atm. Calculate the initial temperature of the polystyrene sample. Be sure your answer is rounded to the correct number of significant digits. °C thermometer. insulated container water sample. a calorimeter 區 OU Ar

Energy in the amount of 5.0 J is added to 0.50 g pieces of aluminum, copper, and magnesium that are initially kept at 22 °C. The molar heat capacities of these metals are 24.3 J/(mol·°C), 24.5 J/(mol·°C), and 24.9 J/(mol·°C), respectively. Which piece of metal will have the highest temperature and what is that temperature?

When 15.00 mL of 3.00 M NaOH was mixed in a calorimeter with 13.10 mL of 3.00 M HCI, both initially at room temperature (22.00 °C), the temperature increased to 29.60 °C. The resultant salt solution had a mass of 28.10 g and a specific heat capacity of 3.74 J K- g-. What is the heat capacity of the calorimeter (in J/°C)?Note: The molar enthalpy of neutralization per mole of HCl is -55.84 kJ mol-1
