A chemist carefully measures the amount of heat needed to raise the temperature of a [m] kg sample of a pure substance from −9.4°C to 14.2°C. The experiment shows that 1.2 kJ of heat are needed. What can the chemist report for the specific heat capacity of the substance in J⋅g−1K−1? Your answer should have 2 decimal places.

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 6.20 kg of water at 24.9°C. During the reaction 51.9kJ of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath in Celsius, do not include the unit only the value. The specific heat capacity of water under these conditions is 4.18·J·g−1K−1.

In this disease there are different stages. The symptoms generally develop slowly over years. Some symptoms include slow and shuffling gait, and tremors. The progression of symptoms is often a bit different from one person to another due to the diversity of the disease. This would be a description of:

___________ ____________ ___________ ___________ is characterized by worsening neurologic function (accumulation of disability) from the onset of symptoms and as either active (with an occasional relapse and/or evidence of new MRI activity over a specified period of time) or not active, as well as, with progression (evidence of disability accumulation over time, with or without relapse or new MRI activity) or without progression.
