Provide the definition of the second law of thermodynamics. How does the second law explain why heat travels from a substance at higher temperature to one at lower temperature?

Use a commutative law to write an equivalent expression.

$$5 x+y$$

State Henry’s law in your own words.

Which law forbids the attainment of the temperature of absolute zero?

What do findings of fact and conclusions of law mean?

determine whether the Law of Sines or the Law of Cosines is needed to solve the triangle at the left, then solve the triangle. Round your answers to two decimal places. A = 45°, B = 26°, c = 20

Express the Law of Sines in terms of only the cosine function.

Write an equivalent expression using an associative law.

$$(3 x) y$$

Determine whether the Law of Sines or the Law of Cosines can be used to find another measure of the triangle. Then solve the triangle. $a=8, \quad c=5, \quad B=40^{\circ}$

Assume triangle $ABC$ has standard labeling and complete the below.

Decide whether the law of sines or the law of cosines should be used to begin solving the triangle.

$$A, B, \text{ and } c$$

Estimate the activity and activity coefficient for $\mathrm{CS}_2$ at $x_{{ }^{C S_2}}=0.722$ using the data in Table for both a Raoult's law and a Henry's law standard state.

Assume triangle ABC has standard labeling and complete the following.

Decide whether the law of sines or the law of cosines should be used to begin solving the triangle.

$A, C$, and $c$

Assume triangle $ABC$ has standard labeling and complete the below.

Decide whether the law of sines or the law of cosines should be used to begin solving the triangle.

$$b, c, \text{ and } A$$

Write an equivalent expression using an associative law.
