Endothermic processes: are those in which occurs the absorption of heat.
the change of enthalpy (ΔH) is greater <span>than zero.

hope this helps!
Answer:
temperature increases with increase in atmospheric pressure
To solve this problem, we use the formula:
C1 V1 = C2 V2
where C is concentration and V is volume
15% * 1000 mL = 65% * V2
V2 = 230.77 mL
<span>So about 230.77 mL of 65% stock solution should be diluted
with water to 1000 mL to make 15% solution.</span>
