<h2>Answer : Option A) Arm and leg muscles and option D) Striated or skeletal muscle</h2><h3>Explanation : </h3>

Voluntary muscles are those muscles which are and can be consciously controlled.

These includes biceps, triceps which are the muscles that are present in arms.

The leg muscles are also voluntary muscles, with addition to this the striated or skeletal muscles are also classified as voluntary muscles.

It is seen that most of the skeletal muscles are attached to bones by bundles of collagen fibers known as tendons are controlled voluntarily.

A backpacker collects snow at 0°C, and places it in a cooking pot on a camp stove. It takes 643 kJ of heat energy to melt the sn
frutty [35]

Answer:

mass (m) of the snow that the backpacker collected= 0.855 kg

Explanation:

Given that:

Q = 643 kJ = 643000 J

ΔHfusion = 6.02 kJ/mol = 6020 J/mol

number of mole of water H2O = \frac{mass (m)}{18}

c = 4.18 J/g⋅K

ΔT = 100 K

Since there is a phase change from solid to liquid; then :

Q = Q_s + Q_l

ΔH = \frac{q}{mol}

However without the given mass; we substitute \frac{m}{18} for the number of moles; so:

Q = \delta H * \frac{m}{18} + m*c * \delta T

643000 =6020 * \frac{m}{18}+ m * 4.18 * 100

m = 855 g

m = 0.855 kg

mass (m) of the snow that the backpacker collected= 0.855 kg
