Robert is instructed in a lab experiment to first record the ambient temperature of the room. to do this, he holds the thermometer under a bright light to accurately read it. he then reads and records the data as 33°c. what error, if any, and effect occurred when performing this lab step?
a) the actual temperature of the room is 33°c. robert performed the steps accurately.
eliminate
b) the actual temperature of the room is lower than 33°c. robert misread the thermometer.
c) the actual room temperature is lower than 33°c. the added heat from the light caused the temperature to be too high.
d) the actual temperature of the room is higher than 33°c. robert should have used the fahrenheit scale, which would have registered higher.

The correct answer is letter C, the actual room temperature is lower than 33°C. The added heat from the light caused the temperature to be too high. 

Light is a form of energy that emits heat as its by-product. The thermometer does not have the ability to distinguish which kind of temperature it's getting, that's why it reads the whole environment as a whole. This was the error that Robert made in this situation. 

Environmental science studies the interactions between the physical, chemical, and biological components of the environment, including their effects on all types of organisms. earth science (also known as geoscience), is an inclusive term for all sciences related to earth (geology, meteorology, oceanogr maphy, etc).  although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm.    environmental and earth science study the interactions of four major systems or “spheres” (figure 8.6).  the  geosphere  consists of the core, mantle and crust of the earth.the  atmosphere  contains all of the earth’s air and is divided into troposphere, stratosphere, mesosphere, thermosphere and ionosphere.the  hydrosphere  contains all of the solid, liquid and gaseous water on earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found.  ninety-seven percent of the hydrosphere is found in salty oceans, and the remainder is found as vapor or droplets in the atmosphere and as liquid in ground water, lakes, rivers, glaciers and snowfields.  the  biosphere  is the collection of all earth’s life forms, distributed in major life zones known as biomes:   tundra, boreal forest, temperate deciduous forest, temperate grassland, desert, savannah, tropical rainforest, chaparral, freshwater, and marine.although the four systems have their unique identities, there is substantial interaction between them.  environmental scientists study the effects of events in one sphere on the other spheres. for example, a volcanic eruption in the geosphere may cause profound direct and indirect effects on the hydrosphere, atmosphere and biosphere as follows: example 1 (volcano)    on may 18, 1980, mount saint helens, in the state of washington, erupted.  this event altered the surrounding environment, and provided scientists with an opportunity to study the effects of volcanic eruptions on the geosphere, hydrosphere, atmosphere and biosphere.  such studies are vital because volcanic eruptions will continue to occur, and will have increasing impact on humans as people continue to settle lands closer to dormant volcanoes. the following are but a few of the myriad of interactions resulting from a volcanic
