Answer to Problem 1GST

The steam is actually in liquid state. Water evaporates out of the coffee cup and as it rises, it cools and condensation into tiny liquid droplets. Hence, the steam is actually composed of tiny liquid droplets.

Explanation of Solution

Evaporation is the conversion of water from a liquid to a gas state when subjected to heat. This absorbed heat helps the molecules to escape the liquid surface and become a gas. Condensation is the conversion of the water from a gas to a liquid state. It is the reverse process of evaporation. The water molecules release energy that was absorbed during evaporation.

The liquid in the coffee cup is below the boiling point of water and the process of evaporation takes place in it in which involves in the conversion of liquid water into the gaseous water.

The molecules in the surface of the liquid gain enough energy to escape from the liquid surface and become a gas in the atmosphere.

However, the atmosphere can only hold too much of water in it. A point reaches where the air above the coffee cup becomes saturated, and attains dew-point.

At dew-point, atmosphere can no longer hold enough water vapour molecules and must condense back into liquid water. That is when condensation takes place and the process that happens above the steaming cup of coffee.

Some of the water molecules that evaporates causes the atmosphere right above it to reach the dew point. A portion of the water vapour condenses back into tiny droplets of liquid water, which one then can see as fog or steam.

The company you work for has been hired to perform geological mapping and mineral potential assessment in a third-party area. During your fieldwork, you discovered a shear zone (SZ) with a general attitude of 0°/90°, approximately 1 km long and 2 m wide, which occurs over very weathered rocks with a schist appearance and contains quartz veins and veinlets with boxworks showing Fe oxides (see figure). The chemical analyses of the samples you collected gave interesting values ​​of 6 to 14 ppm of Au. Your boss, very free, asked you to prepare a quote for the execution of an exploratory drilling hole for two different orientation conditions (60° and 70°) in order to investigate: the continuity of the mineralization at depth, what the host is and whether there is also mineralization on both sides. For this, your boss will tell you that the hole should intercept a ZC 100 meters below the surface, where the rock will certainly be fresh, and that the entire hole should be chemically applied.…
in the block diagram above there are 16 events to put in order of their occurrence. There areno letters to designate the folding and unconformity events but there are blanks for thoseevents. You will see numbered blanks 1-16. Starting with the oldest event at number 16,work your way up to the youngest event at No. 1.
