# Thermal Physics Questions extended essay help biology Technology essay help

Two different objects are in thermal contact with one another. The objects are at different temperatures. The temperatures of the two objects determine A. the process by which thermal energy is transferred. B. the heat capacity of each object.

C. the direction of transfer of thermal energy between the objects. D. the amount of internal energy in each object. The specific heat capacity of a metal block of mass m is determined by placing a heating coil in its centre, as shown in the diagram above. The block is heated for time t and the maximum temperature change recorded is ??.The ammeter and voltmeter readings during the heating are I and V respectively.

The specific heat capacity is best calculated using which one of the following expressions? A. c = B. c = C. c = D. c = The specific heat capacity of a metal block of mass m is determined by placing a heating coil in its centre, as shown in the diagram above. The block is heated for time t and the maximum temperature change recorded is ??. The ammeter and voltmeter readings during the heating are I and V respectively.

Which one of the following is not a source of error in the experiment? A. Some thermal energy is retained in the heater.B. The thermometer records the temperature at one point in the block. C. Some thermal energy is lost from the variable resistor in the circuit. D.

The block is heated at its centre, rather than throughout its whole volume. (1) A container holds 20 g of neon (mass number 20) and also 8 g of helium (mass number 4). What is the ratio ? This question is about modelling the thermal processes involved when a person is running. When running, a person generates thermal energy but maintains approximately constant temperature. (a)Explain what thermal energy and temperature mean.

## Final Paper TED talk

Final Paper TED talk.

Overview of the assignment: You will find a TED talk on a topic you’re interested in (I have provided a list of TED talk examples later in this document). In 4 pages, you will critique the talk, explain the main psychological points that are discussed, and enhance the reader’s understanding of the talk’s topic by finding a peer-reviewed journal article related to the talk’s main psychological points. How to structure the paper and what to write:

1. A STRONG INTRODUCTION: In a short paragraph, introduce what you will be talking about in your paper. I like to know : a. the title of the TED talk b. the main psychological topics covered in the talk c. a brief description of how the article you chose relates to the talk. **Remember that you’re just touching on these three things in this paragraph to give me an overview of what to expect reading your paper. The detailed explanations of each should come later in your paper (continue reading for more info)
