have very little rainfall as less than 50 cm a year with extreme temperatures and very scare vegetation. The fact that deserts are so dry the temperatures can change drastically‚ during the day temperatures can be as hot as 32 degrees Celsius‚ but at night temperatures can drop as low as -4 degrees Celsius because when the sun goes down there is no moisture in the air to trap the heat so it escapes into space creating cool temperatures. The organisms that can be found in this ecosystem are the

solid that looked like tiny crystals at room temperature. After putting it in the flame‚ the CoCl2 turned the flame purple and there were many sparkles. Na2SO4 The Na2SO4 was a small white solid particle at room temperature before the flame. Putting it into the flame caused the flame to instantly turn orange-yellowish. CaCl2 The compound CaCl2 was a white‚ hard‚ and chunky substance at room temperature prior to burning it. Holding it in the flame

* MACRO ANALYSIS 1. If we look the map of Peshawar we came to know that railway station‚ airport and other five hotels are within 30 minutes drive from the site‚ so the site is feasible on macro level. 2. There are two types of architectural styles in Peshawar. The architecture towards the main city is very detailed and classical while towards the new localities we observe modern structures of concrete. Since our site is located in the new locality of modern structures so the architectural

The purpose of this lab is to understand how temperature influences the texture‚ and firmness of fondant‚ and fudge. Materials and Methods: The ingredients that were used for the fondant recipe were 200 grams of sucrose or better known as table sugar‚ and 118 mL of water. The 118 mL of water and 200

The character goes for about an hour with no sign of the road‚ while assessing the map he hears a metallic pop and a piece of his binding has popped out. The character is trying to find the piece of his binding and while he does this his body temperature begins to lower after
