A. The kinetic energy of the food particles increased, causing the food temperature to rise.
B. The thermal energy of the food increased
Explanation:
The grilling of the meat increased the thermal energy which cause the kinetic energy of the food particles to increase thereby causing the temperature of the food to rise.
Heat is a form of energy known as thermal energy. It results from the difference in temperature between two bodies.
When a body is heated, the particles of the medium if solid as in the case of the meat begins to vibrate about their fixed point.
Temperature is directly proportional the average kinetic energy of a particle and so the particles gain more kinetic energy.

Answer:
Reaction is shifting left toward reactant side
Explanation:
4CuO(s) + CH₄(g) <=?=> CO₂(g) + Cu(s) + 2H₂O(g)
--------- 0.22M 0.67M ------- 1.30M
Qc = [O₂(g)][H₂O(l)]²/[CH₄(g)] = (0.67)(1.30)²/(0.22) =5.12
Kc = 1.1 < Qc = 5.12 => Reaction is shifting LEFT and reactant concentrations are increasing with product concentrations decreasing. Qc will be decreasing and final Kc value will be lower than original Qc upon reaching equilibrium stability.

FYI Note => For reaction mixtures the following is a good guide to reaction response to applied system stress. Note the conclusion follows the direction the inequality symbol is pointing.
Kc < Qc => Rxn system is shifting Left
Kc = Qc => Rxn system is at equilibrium
Kc > Qc => Rxn system is shifting Right

Explanation:
the giraffe doesn't need carbon dioxide
Answer:
The vapor pressure at 60.21°C is 327 mmHg.
Explanation:
Given the vapor pressure of ethanol at 34.90°C is 102 mmHg.
We need to find vapor pressure at 60.21°C.
The Clausius-Clapeyron equation is often used to find the vapor pressure of pure liquid.
We have given in the question
And 
is the Universal Gas Constant.
Taking inverse log both side we get,
