Metal has a higher thermal conductivity than plastics
so when it is touched , large amount of heat flows from hands to the metal and hence we feel colder.
so touching plastic will be hotter because of low heat transfer from the hand to plastic
Add Answer to:
One is made from metal, and the other one is made from
plastic.

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...

Consider the information provided in the Hot Coffee Lawsuit. What might be the possible implications for the Restaurant Industry? What might be a long term impact? In 1992, Stella Liebeck spilled scalding McDonald's coffee in her lap and later sued the company, attracting a flood of negative attention. It turns out there was more to the story. The case is now famous but when Stella Liebeck burnt McDonald's coffee she would never know that it would still be talked about...

I don't understand what calculations I would have made to create
the buffer solution from Part D of the lab. I understood the
procedures I took to create the solution but when the report asks
to show the calculations used to prepare the buffer solution I am
not sure other than mixing the volumes indicated in the procedures
section.
