Two blocks of platinum have a temperature of 200°C. One block has a mass of 10 g, the other block has a mass of 100 g. Do the bl
Katarina [22]

The two blocks have the same amount of thermal energy.

<h3>Effect of temperature on different mass objects</h3>

Due to platinum metal, the thermal energy is equally distributed in the whole metal so that's equal distribution the thermal energy of both blocks will be the same so we can conclude that the two blocks have the same amount of thermal energy.

3. Astronomers use various tools to gather evidence in support of the Big Bang
katrin [286]

The Big Bang theory is one of the ones used most frequently nowadays to describe how the cosmos came into being.

<h3>What does big bang theory state?</h3>

According to this theory, the universe formed 13.8 billion years ago as a result of the primordial atom, a single particle, exploding and generating an unprecedented cosmic disaster. The universe is always expanding, according to the same theory.

The key supporting data for the big bang theory are:

The galaxies to getting further and distant from us. This distance is taken at high speeds. In other words, the distance between galaxies is inversely correlated with their spacing velocity. Our perception of galaxy dysthanization occurs because the universe is continually expanding, according to this data, which is known as the "Hubble Law," and this hypothesis also explains that The cosmos has already been unified.

According to the big bang theory, the cosmos was extremely hot at the time of its creation; if this is accurate, we should find some proof of this warmth. Radio astronomers discovered this proof when they noticed that microwaves with a temperature of 2,725 degrees Kelvin included cosmic background radiation. This radiation is perhaps proof of the universe's high temperature.

Last but not least, the Big Bang most likely contributed to the abundance of hydrogen and helium elements.

List three different types of chemical reactions, write the generic description, and give a brief description of each.
slava [35]

Explanation:

  1. Combination or synthesis reaction
  2. Decomposition or cracking reaction
  3. Single replacement or single displacement

A combination or synthesis is a type of reaction that involves the formation of a single product from tow or more reactants:

            K + J → KJ

The formation of a single compound form the union of their constituent element falls into this category of reaction.

The large and negative heat of formation is the driving force for this reaction.

A decomposition or cracking reaction is one in which  two or more products are formed from a single reactant:

     TK → T + K

The breaking down o a compound into its individual components like elements and other compounds falls into this category.

The driving force for this type of reaction is the high positive heat of formation and instability of the compound.

A single replacement or single displacement reaction is one in which a substance is replacing another.

   TO + P → TP + O

The replacement of a metallic ion in solution by a metal atom higher in the activity series than the metal in a solution falls into this category of reaction.

Nat2105 [25]

Answer: Bubble algae are caused by lighting, nutrients and bubble algae spores. The spores were probably on the live rock. The lighting is a side effect of trying to keep photosynthetic corals.
