Physical Science Final Review

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

How do you calculate heat (Q) released or absorbed?

Back

Q = m * c * ΔT, where m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What is the specific heat of aluminum?

Back

0.21 cal/g° C.

Front

What is the formula for calculating heat released when aluminum cools from 100° to 50°?

Back

Q = m * c * (T_initial - T_final) = 10g * 0.21 cal/g° C * (100° - 50°) = 105 J.

What is the chemical formula for Nitrogen Triiodide?

Back

NI₃.

Front

What is matter?

Back

Anything that has mass and takes up space.

Front

What are atoms made up of?

Back

Atoms are made up of subatomic particles.

Front

What is the formula for the compound formed by Ca²⁺ and Br⁻ ions?

Back

CaBr₂.

Front

What is the definition of a chemical bond?

Back

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of atom, while a compound is made of two or more different types of atoms chemically bonded together.
