The addition of 115.0 g potassium fluoride to 603.0 mL of water (d = 1.00 g/mL) causes the temperature to rise 3.41 °C. What is the ΔHrxn for KF? (Assume cp = 4.18 J/g oC.)

Describe the magnitude of the buoyant force

Asap at one point in history people could measure temperature by looking at the volume of a sample of gas. suppose a sample in a gas thermometer has a volume of 135ml at 11.0°c. indicate what temperature would correspond to each of the following volumes: 113 ml, and 155 ml.
