Temperature Changes Flashcards
What is an exothermic reaction?
A reaction that releases heat to its surroundings.
True or False: The temperature increases during an exothermic reaction.
True
What instrument is commonly used to measure temperature changes in chemical reactions?
A thermometer.
Fill in the blank: The temperature change (ΔT) is calculated by subtracting the _____ temperature from the _____ temperature.
initial, final
What is the formula to calculate the heat released in an exothermic reaction?
q = m × c × ΔT, where q is heat, m is mass, c is specific heat capacity, and ΔT is temperature change.
Multiple choice: Which of the following is NOT a factor affecting temperature change in an exothermic reaction? A) Concentration B) Volume C) Temperature D) Color
D) Color
What safety precautions should be taken when measuring temperature changes in exothermic reactions?
Wear safety goggles and gloves, and work in a well-ventilated area.
True or False: The specific heat capacity of the solution affects the extent of temperature change in an exothermic reaction.
True
What is the significance of monitoring temperature changes in exothermic reactions?
It helps in understanding the reaction kinetics and thermodynamics.
Short answer: Why is it important to record both initial and final temperatures in an exothermic reaction?
To accurately calculate the temperature change and assess the heat released.
